A careful study and analysis of more than 35,000 pages of self-improvement materials published in the past 100 years leads to the conclusion that there are really only 10 basic keys to optimum performance and success.
There are no dead optimum performers, are there? To achieve even minimal performance, you have to be, act, and feel alive. If you don't have the energy to do whatever it takes, you'll never perform up to your true potential.
Until you know what's important, you're spending the only life you have on things that simply don't matter. Lacking direction and purpose, you're powerless to make a real difference in your life. However, all self-imposed limitations are removed when you tap into the infinite power generated by 'working from your heart,' fulfilling a clearly defined mission.
Even though you may have a passion for what's most important, until you also believe that you can make a real difference in your life and those around you, nothing's going to happen. Nothing is produced, nor even attempted, until you believe in yourself enough to transform your passion into action.
