The route that helped me up the first steps was:

YouTube David Goggins or read his book Can’t Hurt Me. (Physical) There’s also Jordan Peterson lectures from when he taught in a classroom. (Mental) Or watch the movie Mully, which is a true story and not loosely based.(Faith) Basically just have to find something that you can either relate to or feel connected with. And motivation is nothing without action. Good luck!! You got this!!!
