Having Someone That Pushes You, Like Ain.

It's more important to have a relationship with someone that pushes you than just being the leg lock guy or jim. What really improves your knowledge is finding some one junior who wants to learn something, and sitting down and having to explain it to them. The act of explaining something to someone forces you to really think about things in the simplest possible terms. I've actually had my big insight since you jitsu not because someone told me something, but because i was explaining something to a student or senior person.
