Being in the Right Company

In the company of the right people, in the seat of love, one feels and believes anything is possible. In the company of the wrong people, in the grip of fear, one believes it is not possible.
This pretty much sums up my climbing life.
Climbers look at a line, a piece of rock and say, sure I can find way up this. And then they just keep trying despite all the evidence to the contrary. Hundreds of failed attempts.
Then one person would figure it out and do the one move that seemed impossible.
Then one by one, everyone would do it too.

What is the one thing you think is impossible?
Find the people doing it and find a way to be with them.
