Impulsiveness is a personality trait, it doesn't change, it's part of who you are. It comes from preferring to take information instead of making decisions. Some people have it and some people don't. For the people who don't have it, it would seem like a character flaw. But for the people who do have it, it seems like the most natural thing in the world.
You can of course force yourself to be diligent, but it'll make you very stressed. (hint: startups are stressful).
You can only force yourself if you see a value thats attainable in the foreseeable future.
If something is of low value, low importance, and boring, why would you want to force yourself to do it? It doesn't make any sense. I'd advice you to defer it and do something that's more interesting and more valuable while you can.
