It's feeling the sense of responsibility, the sense of ownership, to step in, to try to solve any problem - and the humility to step back and embrace the better ideas of others. Your end goal, is what can we do together to problem-solve. I've contributed my piece, and then I step back.

G.P.A.’s are worthless as a criteria for hiring, and test scores are worthless. We found that they don’t predict anything.

What we care about is, when faced with a problem and you're a member of a team, do you, at the appropriate time, step in and lead. And just as critically, do you step back and stop leading, do you let someone else?
