Keep a grateful journal. Every night, list five things that happened this day that you are grateful for. What it will begin to do is change your perspective of your day and your life. If you can learn to focus on what you have, you will always see that the universe is abundant; you will have more. If you concentrate on what you don't have, you will never have enough.
For me at this time in my life I recognize that everything is about moving closer to that which is God. And without a full, spiritual center - and I am not talking about religion, I am talking about without understanding the fullness from which you've come you can't really fulfill your supreme moment of destiny.
The older I get, the more centered I become and the more I think I really know about myself. What I know is that what other people do doesn't really have any effect on me.
