They say the hardest part of a journey is getting out of the gate.
Taking that hesitant first step.
Accepting that you have been unsuccessful (not failure, mind you) and the decision to start anew.
Because once you start, there is no looking back; the momentum will carry you forward.
No room for the 'What am I going to achieve, let me be happy here' feeling.
It gets taken over by 'I have already started, let me reach the end' thought.
So far, So good.
