Just Do It For expert motivator Jim Rohn, success is no mystery--it's simply a matter of discipline.

When he was 25, Jim Rohn had pennies in his pocket, no money in the bank and creditors calling. He was straight off an Idaho farm, clerking in a store, and didn't have much planned for the future. Then Rohn met Earl Shoaff-an entrepreneur who had made a fortune in vitamins-and Shoaff told him his future would look exactly like his recent past . . . unless he made some big changes.

Like what? For starters, Shoaff told him he had to face the fact that it wasn't the government or taxes or competition that was keeping him down. What was? Rohn's own thinking about success: "My philosophy was all wrong," says Rohn. "I was preventing myself from succeeding."

So Rohn set about discarding his old thinking and adopting new disciplines for sharpening his skills and goals. "Do that," said Shoaff, "and you'll make millions."
