Things I've learned:
[1] Having an opinion is easy, but knowing how and when to say it out loud is hard -and- takes practice.
[2] People can teach you things or tell you things. Surround yourself with those who teach.
[3] A short pencil beats a long memory.
[4] Think twice before speaking once.
[5] Don't yuck someone else's yum.
[6] Be curious, not judgmental.
