Money is one of the things that motivate people to excel.Whether we like it or not, many things we do for someone is related directly or indirectly related to money. If we don't get a salary, how many of us would work? Give a salesman an incentive or a percentage of the profit, you'll see his sales figures jump up. Sadly some people are motivated to even cast their vote by the lure of money. Request an employee to stay back and work overtime or Offer money for an employee to stay back and work, you will see that the latter works better. Yes, there would be a group of people who depend on a sincere appreciation of their good work as a good motivator, such people need to be respected and be made aware that their efforts have been noticed. For such people a pat on the back, thanks a small memento given at a small get together keeps them to motivated.
