Don't worry about it, its a myth IMO that every single thing you do should be aligned as such that its fulfilling you on some deep personal spiritual scale (im scrubbing this toilet so I can have a clean and happy home for my wonderful family...).

Its true that if you really sit down and think about it you should be able to find some reason why you're doing it at all, but there are so many small and frankly dull tasks in life that you don't have time to sit and think about where they all sit in the greater scheme of things.

Indeed people forget that actually sometimes its not something you want, its that the alternatives are worse. I don't want to clean my toilet, but then I don't want it dirty. I don't want to go shopping on my day off, but then I don't want to have no food all week. I don't want to go to work but having no wage and reducing my chances of getting a good one in the future is worse. Yes sometimes you want to do something, but only compared to the alternative.
