Resourcefulness
I finally figured out the attribute that makes me relate the most to peers. No matter the situation they are in: resourcefulness.
The parameter that changes if you go under in dire circumstances or if you wiggle your wait out. To see a little light in the worst situations possible, you need to be resourceful. Resourceful with good thoughts, solves and next steps.
No matter the stress, no matter the crisis, being resourceful helps you take the next step and navigate it.
After the last years of entrepreneurship, I come to appreciate this as pretty much the single most important thing that drove me through even the deepest lows and most clueless moments.
