How to Trick Your Mind to Find Rewards in Subjective Things That Aren't Actually Coming to You

How do we trick our mind to find rewards in subjective things that aren't actually physically coming to us? I'll tell a brief anecdote about an experiment. It was done where they looked at kids in schools. And what they found is those kids drew at a much lower frequency. They somehow lost the intrinsic pleasure of drawing. Because they were used to getting an extrinsic. Suddenly an ex they associated the drawing with less reward. If you attach all that plasticity, all that brain rewiring to the celebration and only to the celebration, you can erase a lot of valuable content that you're bringing en route to that goal.
