Knowing clever tricks in your early 20s is not necessarily a good thing as you may think. The plot is is you know something others do not, adaptive to trends, then ka-ching. So the one advantage you have is that you find out a new market. But you don't have deep knowledge of any field at all if you spend too much time on the trick. 20s is the best time to learn. And since any business model only works for a certain time. There is a high chance you will end up in your 30s without a hirable skill.
