First of all I think: You just love yourself. Period.
What you describe as “shortcomings” is just your minds interpretation of yourself, it doesn’t have to be true at all. Loving yourself involves understanding who you are and how you function without judging yourself or seeing it as your flaws.
There is no such thing as good or bad personal traits. They just are. The challenge is to be able to direct yourself in the positive direction that will benefit you.
F.ex.: Someone who has a strong temper might use that trait positively, and transform the anger into persistence, passion, strenghth of will etc.
So in my opinion it’s all about finding out who you truly are and become in control of your thoughts, feelings and your own reality. 🙂
