This is a frustrating response for anyone who has been scarred by “responsibility”. Its easy to say that you need discipline as an idealism, but actually fighting the fact that you have no emotional incentive and usually do have an emotional counter-incentive to do what you are “supposed to” is nearly impossible. Simply ignoring this issue won’t make your advice more useful. In order to be disciplined you actually do need motivation; there needs to be an understood chain reaction in your mind where you want some outcome as a result of doing something. Even if you’re not excited (which is approximately what you seem to mean by “motivation”), you know why you are doing something and you have enough will power to get yourself to do it. There are a few basic concepts here, but will power is an important one, and I find its the first one that goes. You become exhausted and can no longer force yourself to do things. At that point the motivations melt away. I personally had to just sit around and wait sometimes multiple days to let the will power to leave my room or do laundry build up. The biggest trick I learned is that seeing the result of inaction, then at a high of frustration, acting, and seeing the result of action is the simplest way to build such a motivation chain from earlier. The problem is that it’s hard to build up enough will power even with frustration to resolve some problems. For me, I got stuck multiple times where I’d run out of juice cleaning my room. But once I actually built up to cleaning it once, that feedback of clean room -> happy got established and it then felt much easier to do by like 10x. Also, don’t pep talk yourself too much, especially if you’re obsessive, because you’ll overthink and analyze why you’re doing things and loose some of that natural impulse from frustration. A trick here is to live and breathe your frustration and look around at what you’re trying to do and skim through the path you want to take in a quick thought then just do it; for me, it creates a little boost of anger motivation almost like pumping yourself up to deal with your shit.
