Life is a circle of happiness, sadness, hard times, good times. If you are having hard times have faith that good times are on the way.
If you don’t believe in yourself, nobody will. Don’t expect others to see gold where you can only see dust. If you don’t believe in yourself, if you don’t believe that you are a capable, a worthy human being, chances are that nobody will. You will act on that belief and people will treat you based on what you think about yourself, based on how you treat yourself and based on how you act and behave in the world.
