As someone going through this right now (turning 32 in October, eek) I've come to realize a few things that have helped.
"Good enough" is an all encompassing set of criteria. You can be the most brilliant person in the world, but if you are unable or unwilling to take the necessary risks to achieve X, then you re not good enough. If you're too risk taking, that's also not good enough. Everything plays into that.
Like a former F1 driver whose name I can't remember said in a podcast once: "Yeah I was good. I was really good. On my best days I was faster than Schumacher, Senna, Prost, and all of them" ... "So why weren't you champion?" ... "Well that's the thing. I was amazing on my good days. The real champions, the ones that make history, they don't have bad days or good days. They're _always_ at their best."
The other realization: You play the cards you've got, not the cards you wish you had. Wherever you are right now, whatever you've got in terms of skill, assets, connections, etc ... that's what you've got to work with. Focus on playing the hand you have the best way you can.
