It is necessary only to put "it is necessary" above "I want."
The secret of motivation is that it does not exist. There is only what is "necessary" and what "I want", as well as understanding that for the sake of this "must" have to step over all their Wishlist. Therefore, the fastest is the one who needs to go to the toilet and the one who runs away from the dog. They do not want, they Need. One tries to avoid shame, the other - to avoid pain. The quickest is the one who wants to live. To live a full life, to feel comfort, not to face shame, resentment and pain, to be loved, happy and contented with yourself. We are equally capable of running away from something terrible and running towards the bright and desired.
