Jordan Peterson had a nice distinction about this: there are things you want to do and things you want to BE WANTING to do. I.e. you want to eat a cookie, but you want to be wanting to go to the gym.

In reality, it's pretty hard to consciously make yourself want something (at least for most people), as our conscious brain does not have that much of an effect on our emotions. In practice, what I've found out I (my conscious brain) can do is alter my circumstances - don't store nice food at house so that it's harder to snack, work from the office (not from home) so that it's harder to procrastinate or get so fat that I no longer feel good in my body.

Or that you think you want to do, but your subconsciousness knows better.

My subconsciousness wants to eat, sleep, fuck and play video games. I'm not sure I want to be taking its advice.

Your subconsciousness doesn't ask for your permission.

Yeah, that's the problem. That's why I'm reading this stuff about procrastination. What's your point? Are you saying I should just give up?

No, I thoroughly enjoy playing Guitar, once I get started I play until my fingertips are hurting. I still have days where I just dont want to pick up the damn thing and put it off.

Many of your desires may well be acquired preferences

Procrastination is and should have definitely more into it. Inaction brings convenience with it and inaction is the only child of procrastination. So, it's due to our inclination to convenience and doesn't say anything yet about the task at hand.

That's the reason people procrastinate on the things at one moment which they don't at others.
