We are capable of far greater accomplishments than we realize. Had I known as a much younger man what I could have been or accomplished in this lifetime, I would have worked even harder and dreamed even bigger. Shoot for the stars, if you fall short you'll still finish beyond your wildest expectations!
2.) Play hard.
If it's worth doing, it's worth your best efforts. I was never the fastest, strongest, quickest, biggest, smartest or most talented. But I always made the first team in sports and succeeded in business because I played harder than those around me and put my guts into every play, every effort, and every challenge I took on.
3.) Be true to your heart.
It's a hollow victory if you know in your heart you didn't play by the rules. Winning at any cost isn't winning anything - it will come back to haunt you. Be true to your heart, play by the rules, never compromise your values or your ethics - you will not only succeed, you'll sleep at night and revel in the satisfaction and happiness of having done it the right way.
4.) Never give up.
Sumner Redstone said it best - "Success is not built on success. It's built on failure. It's built on frustration. Sometimes its built on catastrophe." Nobody always gets it right the first time or succeeds immediately. Everything in the universe must balance out. There are only so many "no's" until the "yes's" start to follow. Failure is your friend because if you keep pushing, success is just around the corner. The winner in most endeavors is the person who just won't give up - no matter what!
5.) Whether you think you can or you think you can't...you're right.
Nothing in the real world materializes until you've thought about it first! You create your own reality in this existence by having seen and thought about it in your mind's eye before it ever comes into being. Negative self talk will only give you negative results. Treat that little man or woman inside as the strong, smart, kind, successful being he or she truly is. Create those positive images and positive feelings of having already achieved your goal, and it will come to pass.
