Self-esteem must be earned! When you dare to dream, dare to follow that dream, dare to suffer through the pain, sacrifice, self-doubts, and friction from the world, you will genuinely impress yourself.
This is all you have. This is not a dry run. This is your life. If you want to fritter it away with your fears, then you will fritter it away, but you won't get it back later.
My best way of making someone admit to something's wrongness is to have them imagine that thing done to them. Suddenly then it all becomes clear.
Life does not have meaning through mere existence or acquisition or fun. The meaning of life is inherent in the connections we make to others through honor and obligation.
