Another approach is that of Torah machziran l’mutav. That is, in addition to learning sefarim specifically on tikkun hamiddos, learn things that deal with the greatness of God and the greatness of man (gadlus haborei and gadlus ha’adam) and from there the yetzer tov asserts itself so that you do what — in the words of the introduction to Missilas Yesharim — “everyone already knows is the right thing but still abstain from doing because of laziness or lack of will.”
This approach is discussed at great length in many sefarim, particularly chabad chassidus. I’m obviously not qualified to say which approach is better. When I finish with either one I’ll let you know. 😉
