[Advice Needed] Techniques for building habits, and the surviving the slow grind.

First time on TRP, hope this fits the rules.

I feel apathetic a lot, I have so many resources available to me but I never seem to be able to make use of them.

Just as a 500 calorie deficit a day can turn the fattest man to a perfect specimen, just an hour or two of work should be able to build lifelong career or life skills.

So I ask you, how do you build habits, what habits have you built and how have you survived the slow grind?

Edit: dang, the title...
