When you think about it, the success of any facet of your business can almost always be traced back to motivated employees. From productivity and profitability to recruiting and retention, hardworking and happy employees lead to triumph.

Unfortunately, motivating people is far from an exact science. There's no secret formula, no set calculation, no work sheet to fill out. In fact, motivation can be as individual as the employees who work for you. One employee may be motivated only by money. Another may appreciate personal recognition for a job well done. Still another may work harder if she has equity in the business.

But you can boil down employee motivation to one basic ideal -- finding out what your employees want and finding a way to give it to them or to enable them to earn it. Here we've gathered some of the best and most interesting motivational techniques used by successful entrepreneurs. We hope they'll motivate you, too.
