Teach everything you know.
Even if it's already been taught 100 times before.
The experiences you've had and the way you word things will be different than the 100 times before.
Because of that, there are people that it will just click for them.
Because you taught it.
@g also, you have audience that those 100 other may don't have.
Trying right now to live this. Thanks.
@g
I think a corollary to this is to write down everything you know to the best of your ability and how one came to discover those things, because other people will always benefit from it.
Even if that other person is just one's future self.
