In part, as you hinted
Jenna, it does depend on where the criticism comes from.
However, criticism of your martial arts is the only way you'll ever know if you're really improving or not, so it is quite important not to be too thin-skinned about it.
My sensei used to pick up on faults in my iai all the time and altho' I never let it show, I was a touch concerned that maybe I just didn't 'have it' as far as swordwork went. There was praise in the mix as well but it is all too human to only notice the negative
.
Then two events came in quick succession.
A fellow student let on that one reason why sensei would point out a flaw in my performance rather than someone elses was that I had a good attitude and sincerely wanted to learn. Also, I was confident enough in myself to 'take it', so I could serve as an example for the others without wilting
.
The other incident was an exception that eavesdroppers never hear anything good about themselves as I overheard sensei and a sensei from another school commenting on how my iai had improved in such a short space of time.
Those two small events helped me maintain my view, that I've ever held, that criticism is not something to be embarassed by but thankful for.
Insults disguised as criticism are another thing entirely.
Some personality types might require that form of 'dominance ritual' to spur them on but not me. I'm sorry to say that I'm of a stubborn personality type which means I can be lead but not driven
. Push on me too hard and I forget all my Zen-like 'bend like willow', dig my heels in and push back (Viking+Celt genes will come out one way or the other) :blush:.
