It's a funny thing about life, once you begin to take note of the things you are grateful for, you begin to lose sight of the things that you lack.
Live your life in such a way that you can say "I love my life" and really mean it.
It doesn't matter what others think. This is about YOU. Create a life that you genuinely love with your whole heart and start with yourself.
Take a deep breath and pause for one minute without doing anything! There did you feel the magic?
If you are truly in love with this world and your life, then you will lose the sense of angst.
