Q: how do you get motivation to do the things you want to/should do
A: if it's something you want to do, then that means you are already motivated to do it. if it's something you should do, then you need to understand a little better why you should. or if you even agree that you should. and if you don't agree that you should, then it really comes down to the consequences/rewards of doing it, etc, whatever agreement is in place between you and whomever thinks you should
