You become what you focus on and like the people you spend time with.
Be happy. Be yourself. If others don't like it, then let them be. Happiness is a choice. Life isn't about pleasing everybody.
Learn to love yourself first, instead of loving the idea of other people loving you.
All that you achieve and all that you fail to achieve are the direct results of your thoughts.
Saying someone is ugly doesn't make you any prettier.
When values are clear, decisions are easy.
