Let me explain it for you. These guys are all crazy, don't listen to them.
1st Dan - knows nothing but how to find the changing room. But he knows he knows nothing. The best black belt.
2nd Dan - knows nothing but thinks he knows something. Gets beat up in class a lot by brown belts.
3rd Dan - Entitled to be addressed as 'sensei'. Gains 50 pounds, buys a new gi.
4th Dan - Opens dojo, fails, goes back to original dojo. Buys sports car.
5th Dan - Opens dojo, succeeds. Takes students to tournaments, ignores rules against coaching from sidelines. Thinks he can still spar. He cannot.
6th Dan - Goes to tournaments and stands around talking with other high Dan ranks. Has run belt sander over black belt so that it's so frayed it is barely holding together.
7th Dan - Might actually know something, but isn't talking. Gets red-and-white panel belt, which curiously is still called a black belt. Starts to add titles like Shihan, Doshi, Big Kahuna, Mostacholli, etc. to actual Dan rank.
8th Dan - Writes a bad book full of bad advice that only students buy and no one reads. Affects a slight Asian accent even if not Asian.
9th Dan - Has a string of dojos, others teach for him. Goes to Hall of Fame banquets that he pays to attend. Trophy wife.
10th Dan - Dies. People talk nice about him.
So, if I were to go by your list, I would want to get to 1st Dan and stop there.
