Best advice you've ever gotten?

Yes because to teach it you actually have to know your stuff not BS your way through. Lol.

I actually had a lot of friends in middle and high school who did that. They would learn, and then pretend they were teaching a class, and would explain the stuff out loud, by themselves in their rooms.

As for myself, I am not sure if there is one piece of [i]advice[/i] I've gotten that stuck with me... but there is one piece of wisdom that changed the way I think. So as a teenager, I was in this very confused phase, where I couldn't really decide what I wanted to learn in college or what to do in life. So my folks took me to this renowned thinker/philosopher guy who they knew through someone. I was expecting someone old and 'wise looking' but instead it was this young guy. Well, young-ish. He asked me what my primary concerns were.

So I started rambling, and finally ended it with, "I'm not sure what I can do to change this world? I mean, what's my purpose?"

And he simply nodded for moment, and then asked me, "Can you name someone who has 'changed' the world or human life?"

I almost began to answer, then I realized what he meant. I couldn't think of anyone who had changed the world itself. We use it as a phrase. That someone changed the world or what someone did changed the world forever. But the more I thought about it, I realized it wasn't really true.

He was smiling by then, obviously sensing my wheels turning. And he added, "It is not our place to change the world. We simply add to it, and leave it. Human life will go on regardless of us. The burden of change is not on any of us. Our purpose is, at best, to contribute something to that stream of life, and maybe find our purpose in that."

That conversation fundamentally changed the way I thought about life in the abstract.

When you have to explain a concept to sombody you have to think of it from all angles and how to break it down such that the other person understands. That fosters a deeper understanding on your part. You’ve no longer just memorized a fact on the surface but fleshed it out.

Everything is under your control and thus your responsibility - if you get a bad grade or don't have the results you desire don't blame anyone else but yourself.

yup true, thats how i learned my school work, idiots asking another idiot for help, i was older in the class so i felt the need to help them which made me understand it more and really got into it.

Don’t stand in dingo poop

True to a point. Those that can't do (for whatever reason), teach.
