In my opinion the key to self esteem is courage. Courage to leave your comfort zone, courage to do something you’ve never done before.
With each encounter into the unknown your self esteem begins to build as you become less afraid of change.
With each new adventure you draw on past examples of strength and begin to believe that whatever happens you can handle it.
Therefore the key in my opinion to building self esteem is to continuously leave your comfort zone.
