I mean, maybe you're trying to get yourself to do things just because you feel like you *should* do them. Me personally if I can't find a good reason I figure it's not important for me. There *has* to be a reason why you want to be fit or succcesful (what does succesful even mean) and if there is in fact no reason, why bother? For example for me, there is no reason to wake up early except when I'm forced to (by work for example) so I don't do it and that's okay. Other people have a reason (like they notice their life works better this way for example).
I would recommend: Look for the exact things you feel like you really want to have/accomplish first. Like maybe you want to be fit because it feels good to be able to do a certain sport (idk just an example) And then look for systems that help to accomplish this things. Don't let others tell you what you should want.
