Those advice go beyond self-esteem, it's rather some philosophy to live a better life.
The most relevant to me are:
* Talk to friends and family
* See your self-esteem grow
* Write down your worries
* Try a low GI for steady energy
* Be naturally sweet
* Stay hydrated
* As simple as a walk
* Swim for self-esteem
* Make your goals personal
* Would someone else say that to you?
* Focus on your abilities
