Success means different things to different people. We each measure success in different ways.
For some, level of income is the measurement; for others, it is the thrill of achievement, of accomplishing something; for others, success is measured by volume, in other words, how many sales you make in a defined period of time.
Goals, targets and seeing how respected leaders achieve success all serve to inspire and motivate us. If we want to accelerate our progress, we need only to find leaders who are doing what we want to do, and then model their effort and activities.
