When you have launched your company, carved out a profitable niche in the marketplace, and now make more money than you know what do with, should you keep pushing to increase your wealth and success?

When Tony Robbins first reached $1 million a year, he thought that he shouldn't try to make any more money. For seven years, his income stayed at that level. "I thought if you want more than a million dollars a year, you have to be a jerk," Robbins tells Inc. editor-in-chief Eric Schurenberg in an Inc. Idea Lab video series.

But during the eighth year of making seven figures, he says, he was on a trip and called home. His housekeeper picked up and told him how grateful she was to be working for him. He then started to think about what he had at that point in his life: five companies, a family, and a home on the ocean. "I thought: If you could be smarter, should you? If you could be more giving, should you? And I thought if you could be anything more, should you? And the answer is yes," Robbins says.

That night he let go of his guilt about being wealthy, which had stemmed from his experiences growing up poor in an abusive home, and decided to build as many businesses and as much wealth as he could.

"The formulators of wealth do more for others than anyone else does. That's the only way to sustain it," he says. "You can get rich by screwing someone, but if you're going to stay rich you have to be constantly help people." 

Robbins says that constantly being hungry and giving back are two key components of success. The most successful people in the world are never satisfied. That's not because of greed, he says--it comes from a passion to build things and help as many people as possible.
