When you do whatever you love you grow.
When you do whatever you hate you get resentful and regress.
Discipline is doing whatever you don't want to do. Yes, you can force yourself to do things you believe are beneficial, but it doesn't matter — you will become resentful and regress — not progress!
Only by doing whatever you love you can progress!
"But everything constructive is hard and I don't want to do it and I need to force myself!"
Exactly! Everything beneficial is "hard" bacause it is constructive — you are constructing, building, focusing energy, opposing the chaos of the universe.
And you don't want to do it because you don't trully understand why you need it and are not used to it. Your body tries to save energy because it thinks that energy is scarce, but it's not — you have unlimited amounts of energy.
To love doing constructive things, you need to convince the body that it is the best way to survive and reproduce. And it is not done through self-talk. The body doesn't understand language — it understands visuals and emotions.
You need to slowly show it that whatever you are doing is good for you. To do that, start doing the action (lifting weights, for example) and focus on the progress, imagining the result it will bring (jacked body, girls, respect snd admiration from others, etc.). Do it and be proud of yourself — you are exceptional and are doing the hard thing to become great.
Take care of your sleep and food, which will allow your body to be in an optimal, healthy state. When you are energetic, you want to do hard things.
And always remember — your focus drives your life — focus on the progress you are getting with each repetition. Pain is just information — use it as a guide. And visualize, visualize, visualize!
