You are never too old to set another goal or to dream a new dream.
C S Lewis

The only thing standing between you and your goal is the BS story you keep telling yourself as to why you can’t achieve it.
Felix Baumgartner

The greater danger for most of us is not that our aim is too high and we miss it, but that it is too low and we reach it.

If you think you can or you think you can’t – you are right.
Zig Ziglar
