What is the difference between an intrinsic reward and an extrinsic reward?

• Intrinsic Reward: Something which appeals to a person's desire for self-actualization or challenge, deep interest and involvement in the work, or curiosity or sense of enjoyment.

• Extrinsic Reward: something that appeals to a person's desire to attain a goal that is distinct from the work itself. Examples can include incentive pay, a luxury vacation given as a reward for generating the most sales, or special recognition for winning a competition or meeting an important deadline etc.

When you reward yourself for anythine you deemed or was interested in then it is intrinsic reward and you rewarded yourself by self satisfactory and happiness.

When someone else rewards you then it is extrinsic reward and it give you profit in some how which maybe satisfactory, money or success.
