A good friend of mine just emailed me today and the one thing that stuck out most in my mind was when he wrote, "It is far better to fail at great things, then to succeed at nothing."
Isn't that the truth?
This applies to so much... training, life, relationships, business, family, and well pretty much everything. In your comfort zone you find just that, comfort. You nuzzle yourself in a corner, whether it's actual or just a spot in your mind, and then you rarely if ever walk away from it. You become happy with the way life has settled upon you. Leaving options to become obsolete, leaves life with no choices.
Inadvertently, self doubt becomes part of the equation. Self doubt doesn't fit into any equation that includes success.
Success doesn't necessarily mean that you have answered all the questions to life, it doesn't mean that money is no longer a matter of importance, it doesn't mean that you stop believing in yourself, and it doesn't mean that you no longer have to try. In fact, all these things become that much more important as you continue grow. With success comes growth, and the acknowledgement that without trying you never know what could have been.
If you question an action that you haven't taken, reflect on it's options, determine the ideal outcome, and visualize how that outcome will affect your life. What happens if the outcome isn't ideal? You learn. You know that you tried. You know that you have something to work toward, or something to change, or something to become better at. You have a chance to grow and to learn, and to recognize that you made an attempt. Regardless, you added an experience, one you never would have had without taking a chance.
