I believe the point of discipline is to do something regardless whether you want to do it or not.
My favorite quote on discipline:
“A modern stoic knows that the surest way to discipline passion is to discipline time: decide what you want or ought to do during the day, then always do it at exactly the same moment every day, and passion will give you no trouble.” - W.H. Auden
Connecting the future outcome you want with your present experience. Running when it’s 40 and rainy sucks to start, but after your warmed up and for the rest of the day you will be glad to have done so. Starting definitely sucks, but if you’re convinced enough in the present that the future state is worth it, you will want to run and you will want to push through it. That’s a skill that can be cultivated.
