You must commit from the beginning to never give up, no matter what it takes! Every person dreams of great success and prosperity, but most of those people fail to fulfill those dreams because they ignore or don't understand the critical importance of accepting personal responsibility for them. To win in business and life in general, you must be willing to pay the price of the success.
The greater the success you desire, the greater the price that has to be paid. Your price will be measured simply in terms of the courage required from you to push forward in spite of the naysayers and obstacles, in the setting of a clear and practical goal, and the determination to reach it.
