What do you consider the three most important attributes of self-esteem to be? For a person with self-esteem that's super low behind closed doors, it goes something like this:
1 - Body Image
2 - Accomplishments (improving body image can fall under this category)
3 - Personal Talents/Intellect
1 - Body Image
2 - Friends' approval
3 - Accomplishments
Aren't 2 ans 3 pretty much the same thing? Also, given that you have average looks, body-image can rely on fitness/weight training accomplishments.
1. Liking oneself (biggest part)
2. Accomplishments (linked but not limited to approval, help the 1.)
3. Body image or friends/family approval/support
