The correct answer is rewards.
There are various types of motivation, but all of them involve some kind of a reward, whether it is something intrinsic, like happiness when you learn/achieve something, or extrinsic, like good grades/money. It is not a secret that we perform better when there is a reward involved because we are anticipating receiving that reward and therefore we try hard to get it.
