What's the word for something that you don't want to do when you're doing it but you want to do it when you're not doing it?
To give a longer explanation, a word for an activity that you're like "I really do want to do this" when you're doing it, but when you're done with that activity, you reminisce about doing it, wanting to do it, and you go back to doing it.
For example, studying would be like that for me. When I'm studying, I'm like "man, I really do want to do this." However, after I'm done studying, I constantly reminisce about studying, not because I feel an obligation to do it but rather because I want to do it (no connotation of compulsoriness included).
