The correct answer is yourself! It is specifically the way you determine your own importance what expresses the quality of your life. It turns out that everything in life can be expressed by one criterion: does it increase your level of happiness or not?
Our self-esteem is like the core of a nuclear reactor. Note that every time you say "I like myself" - you smile and feel better. The other side of such condition is having a sense of authority, confidence, power and strength. It is when you feel that you can set goals and achieve them.
