While willpower may work for some people, what actually works for me (and i believe the majority of people) is self-deception or distraction.

To sleep, use white noise/rhythmic music/soothing voice

To climb a mountain, tell yourself that my next goal is to just reach that particular rock about 100 metres higher

In the gym, make a friend and chat and joke with them while doing your exercises

While sprinting, divide 32 by 13 to many decimal places, as Joey from Friends once suggested.
