I'm a noOb, and can I just say:
A
M
E
N
!
I've made almost every one of those mistakes and learned the hard way.
To other noObs like me, the advice is truth.
I'd like to add an addition to the last: Don't forget your roots. Don't forget that if you succeed, you didn't get there alone. Don't be afraid or too selfish to impart your knowledge on someone who needs it.
We were all noObs once upon a time.
Good post. Peace.
