Question

Hello Rabbi.
It’s very hard for me to stick with something over time. Whether it’s regular study, playing music, writing, or even just cleaning my room. Every so often I do things in spontaneous bursts (finish a tractate / study for a comprehensive exam in two days, scrub every corner of the house, etc.), but I can’t manage to do it consistently (even in much smaller doses). In short, I know how to persist in two things: trying to persist, and failing in that attempt (what you might call second-order persistence). Every so often I tell myself, “That’s it, from now on you’re going to start doing X every day,” and within a week at most I’m back to my old habits. There’s a kind of element of weakness of will in this, at least that’s how it feels (I know that I want to persist, but in practice I don’t do it), which only adds to the sense of frustration.
My question is: how do you persist? And more specifically—how do you persist, and deal with the difficulties involved? (I realize this is a very amorphous question and it’s hard to give clear guidance, all the more so without personal acquaintance. Even general directions and ideas that helped you would be very helpful to me.)
I wait for your salvation…
