Yes, yes, yes. This is the core of the stoic belief, not to be confused with lack of emotion as it has been confused with, nor lack of spirituality, which it has been confused with. Stoic philosophy is actually embodied in the serenity prayer. In this piece I adapted the prayer to be specific to what I read was the stoic view of willpower. https://medium.com/channspirations/the-serenity-prayer-df758d99c956

Gods, please breathe into me the strength to do with serenity that for which I have distaste; the strength to say no to burning desires; and the wisdom to know that my path will lead to what I truly need and serene happiness will ensue.
