Don't complain about what you don't have. Use what you've got. To do less than your best is a sin. Every single one of us has the power for greatness, because greatness is determined by service-to yourself and to others.
What I learned at a very early age was that I was responsible for my life. And as I became more spiritually conscious, I learned that we all are responsible for ourselves, that you create your own reality by the way you think and therefore act. You cannot blame your parents, your circumstances, because you are NOT your circumstances. You are your possibilities. If you know that, you can do anything.
Dogs are my favorite role models. I want to work like a dog, doing what I was born to do with joy and purpose. I want to play like a dog, with total, jolly abandon. I want to love like a dog, with unabashed devotion and complete lack of concern about what people do for a living, how much money they have, or how much they weigh. The fact that we still live with dogs, even when we don't have to herd or hunt our dinner, gives me hope for humans and canines alike.
What I know for sure is that what you give comes back to you. That's not just my theory or point of view, it's physics. Life is an energy of giving and receiving... Those that are greedy, hit a road block where they are alone. Give more than you receive and be grateful for those around you.
