Goals are a means to an end, not the ultimate purpose of our lives. They are simply a tool to concentrate our focus and move us in a direction. The only reason we really pursue goals is to cause ourselves to expand and grow. Achieving goals by themselves will never make us happy in the long term; it's who you become, as you overcome the obstacles necessary to achieve your goals, that can give you the deepest and most long-lasting sense of fulfillment.
The most important thing you can do to achieve your goals is to make sure that as soon as you set them, you immediately begin to create momentum. The most important rules that I ever adopted to help me in achieving my goals were those I learned from a very successful man who taught me to first write down the goal, and then to never leave the site of setting a goal without firs taking some form of positive action toward its attainment.
I believe life is constantly testing us for our level of commitment, and life's greatest rewards are reserved for those who demonstrate a never-ending commitment to act until they achieve. This level of resolve can move mountains, but it must be constant and consistent. As simplistic as this may sound, it is still the common denominator separating those who live their dreams from those who live in regret.
One reason so few of us achieve what we truly want is that we never direct our focus; we never concentrate our power. Most people dabble their way through life, never deciding to master anything in particular.
The truth of the matter is that there's nothing you can't accomplish if: (1) You clearly decide what it is that you're absolutely committed to achieving, (2) You're willing to take massive action, (3) You notice what's working or not, and (4) You continue to change your approach until you achieve what you want, using whatever life gives you along the way.
You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.
