If you don't have a mountain, build one and then climb it. And after you climb it, build another one; otherwise you start to flatline in your life.
I'm always looking for a new challenge. There are a lot of mountains to climb out there. When I run out of mountains, I'll build a new one.
If you look at people that have survived crashing in the mountains and lived up in the snow for 40 days - it's possible to do extraordinary feats.
