Sorry, Alex, but there's too much here to not go through...
Many when giving advice, or insight, forget to ask permission before doing so. It's a fine boundary to cross; and the religious do it most oft, but you can find it in martial arts just as often.
Yes, preaching when not asked for isn't really humble... so before you start preaching, it's a good idea to look at whether or not you are in a position to. I'd agree with that.
Oh, and you're still misusing 'oft'... that form only really works in poetry, hardly in a discussion forum (unless you're being deliberately flowery, for whatever reason... but that's not what your posts have shown), and certainly not in academic language as you are using as an excuse.
A person must choose their teacher, and the teacher likewise, their students. They can be all accepting, or exclusive, it is in their inherent nature, and they will teach best by following it naturally, accordingly.
Now here you start to lose me... you were talking about giving advice or insight, now you're talking about choosing your teacher? I'm not really sure of the connection you're making there... are you saying that a teacher should ask permission before giving advice to the student? Or that the student should be advising the teacher? How is this connected to the former statement?
I have found when you give advice to others... they are not always the most receptive. My poor reputation here, stands for grounds of that. It means nothing that the words might be hollow, or false, or wrong. It is hard to be outright wrong in martial arts, save when something just isn't working for the individual, and they cannot see the shortcoming causing it.
But being receptive toward insights which are truly so for oneself is important- everyone has advice, but if you followed all of it, you'd wind up worse than when you started.
Not to stay on it too long, as discussions on rep are against the TOS you agreed to when you signed up, but the fact that you were offering advice isn't why you got the rep you did, it's more about your inability to listen to constructive criticism, even when you asked specifically for it, not listening when corrected, and basically coming in with a "greatest thing since sliced bread" attitude. You can offer advice as much as you want, but bear in mind it won't be accepted automatically. That's fine, no-one's is. But we deal with it, listen to what is said, and then act accordingly (for the record, sometimes the arguments are baseless, ludicrous, or plain silly... but they're still listened to, and then dismissed only if that's the right response).
But to it... "It is hard to be outright wrong in martial arts"? Uh, no, not really. It's quite easy, actually. Many, many people have managed it, many continue to manage it, many more will manage it tomorrow. In fact, you've managed it yourself quite well.
I'm not sure what you mean in your next paragraph ("being receptive towards insights which are truly so for oneself is important"... uh, are truly what? You don't seem to have a context or subject for that statement...), are you saying that it's important to be receptive to insight which is applicable to yourself? Uh, okay...
I recall a great artist in Greece, the best in masonry and creating statues, took two marble blocks, and had the townspeople give advice as to what was beautiful, and would create the figure based upon their suggestions. With the other block, with his own definition of beauty, he chiseled. When both were unveiled, the town was reviled at what he had created, at their own suggestions, while his own, they agreed without exception was the eye of beauty. The message isn't that he tried to discredit the town, but rather akin to when Buddha explained to the blind man what sight was- you cannot know what it is until you do it, and I like to think Martial Arts applies to both.
Hmm, that's quite a mess of words you've put down there... let's look to the use of language first. The big one is "the town was reviled at what he had created"... look, as we've said to you many times now, using words without understanding their use just makes you look bad. The town could be appalled at what they saw, they could revile it, but to say they were reviled means that the townspeople themselves were the image of horror, not the statue. Seriously, you make such a number of grammatical errors that the claim that they are due to academic requirements falls flat. I'm pretty sure that part of the academic requirements would be that the words are correctly used.
But to your story there... you're just using it to illustrate that doing what everyone says ends in a mess, yeah? The reason I ask is that your end comment about Buddha explaining sight to a blind man has, well, nothing to do with the story you linked it to. The story is about individual perceptions not matching, and attempting to please everyone ending in no-one being happy... and the lesson you associate it with is about the importance of experience as a frame of reference. And I really have no idea what you're talking about when you say "I like to think that Martial Arts applies to both"... both what?
A lot of people think they know what to do, it takes a humble man to be able to accept their advice, not destroy their own picture, and take the elements that do work. Lord knows if you listen to everyone here you'll twist your head into knots- and it's because we are all so different as people and martial artists.
But, to take your situation as a template, if everyone is saying the same thing, and you asked for the advice in the first place, not listening to any of them could be taken as not being very humble.
I don't make hard contact because I am humble- I would like to think. Not because I think I can devastate with a single blow, or annihalate through speed... but honestly, I'm happy with the people I train with. I'd rather let them know I value their safety, over proving a point, in the sense I do not want to lose them as training partners. When they want to put on the pads, and go hard, I'd like to think I'll be there, hopefully matching them. Humility is something behind not just behavior, but our art as well. Is your art flashy, for show... or practical? And why?
Alex, please. "I don't make hard contact because I am humble.." Really? You're going to have a hard time convincing anyone here that's the reason. Especially when hard contact is considered one of the primary reasons for humility and politeness in many dojo... going soft shows a lack of respect for your partners, their ability, and their development in many cases.
I mentioned reiho in Japanese arts earlier... without going into too much detail, reiho (proper etiquette), saho (proper manners) etc are considered essential in Japanese martial arts, and a major reason is that if you didn't show the proper respect you might very easily just be killed during the training. And no, that's not me being poetic. I'm being very literal.
Did you learn martial arts to be great... or help others? It's unquestionable Bruce Lee is a great martial artist, but outside of cinema, you begin to a see a character who was not humble. Who would not admit defeat, or flaw. And that is problem- he was human, and martial artists, and martial arts, are meant for humans, the fallible. Those who know fear, and pain, and with the will to weather it and continue.
Are those really the only reasons you can think of for learning martial arts? Honestly, for me, neither.
Sorry for going philosophical. Humility is difficult, like being perched on a knife's blade. A quote I liked by Bruce Lee sums it up best, "If I said I were weak, you would think me lying. If I said I were great, you'd think me boasting."
No, humility isn't that difficult. It's relative.
