"If you are really great, you will let others discover this fact from your actions." http://ping.fm/ZdzHO

In the final analysis, all that really matters are your actions. You may talk a good story, but no matter how good you are at selling others on your capabilities, eventually you have to perform. It is true that people are generally forgiving and will overlook an occasional failure to deliver upon your promises. Ultimately, though, you must live up to your promises to others if you ever expect to make a lasting impression on them. Make it a habit to demonstrate your abilities before talking about them. Seldom is anything worthwhile achieved without the help of others, and nothing is ever achieved without some form of action. The road to failure and despair is littered with the dreams of those who failed to act upon them.
