Whether it be to do your job, get your schoolwork done, clean your house, work on your creative passion, etc.
Bonus points if you’re someone without reasonable self-control so saying something like “I can only have a cookie after I do this/while I do this” doesn’t work for you and you’re just going to eat the cookie and not do it.
This works very well for me. It certainly helped me get past the notion that I needed motivation before doing something.
I prefer to want to do a thing befor doing it, but I don’t have to.
