Having a rough idea of where you want to go and setting yourself a number of small wins in the right direction could help you. Get into the habit of daily small wins that you know is moving you towards your true north.
As another point, I see systems and habits referenced below. Interesting because I'm midway through Benjamin Franklin's autobiography. Here is what he did:
He worked out a set of virtues that he thought he ought to have, such as temperance, industry, silence, etc.
Using that, he then used the calender method that's proposed a lot on each virtue to instill them as habits!
I'm inclined to say he was an early self-help author but also one that has something other than success in self-help as a justification for his methods.
