If you are pushing yourself to be more and do more... then you have to expect that there will be setbacks. Life doesn't more forward all of the time. There will be dips and bends, side tracks and dead ends.
Expect them and then deal with them. The successful person is the one that overcomes the obstacles, not one that is overcome by them. Your forward journey will be punctuated by falls and even failures.
Expect them, accept them, learn from them and carry on.
