Discipline is bullshit, try understanding
The most profound practice that I've found in my life is meditation. Through meditation and listening to teachers I've realized that all your desires and thoughts are kinda bullshit. This is the idea: whatever you think is wrong. Thoughts are just words in your head, they are not reality. And when you try to describe reality through words it is very simplified and you can never pass all the nuance and complexity of reality through this medium. That means that when you say something, it is both true and not true.
For example: Discipline is good. It is true in a sense that if you use discipline to make yourself healthier, it is good. But it is also bad, in the sense when you use it to suppress your desires to the point where you don't enjoy your life at all. Both are true, and both are wrong.
Whatever you say, it is going to be wrong. Don't say anything. Any thought is bullshit, just perceive it and let it go and be guided in the moment by whatever is right. You don't need theory, goals and whatever else. Just be in the moment and notice that it is all bullshit.
