Motivation will be increased if there are better rewards

If you want someone to do something, giving them a hefty prize sounds like a sure-fire method to motivate them, right?
The difficulty is that studies have discovered that these rewards can sometimes backfire.

The beauty of intrinsic motivation is that it never fades. It restores motivation with each use as long as the activity stays meaningful and exciting to you.

Exchanging a reward for behaviour, on the other hand, is transactional. Placing a reward at the receiving end of an activity implies that there is a cost (the action) as well as a profit (the incentive). It suddenly feels like I'm doing something for a living. You're no longer performing the activity for the sake of doing it. Instead, it serves as a means to an end.

When you reward someone for doing something they are already intrinsically driven to do, it typically leads to a drop in motivation, which psychologists term the overjustification effect. When a person truly requires some type of incentive to engage in an activity, rewards can encourage action; however, reinforcements should be utilised cautiously and sparingly.
