As someone whose major was in economics, let me warn you that most of what you learn in ECON 101 is not directly applied as policy in the real world. It is not that the concepts are incorrect per se, they aren't, but they are rough approximations, with a lot of assumptions that are not necessarily true in the real world. Econ 101 thinking is generally a good starting point to understand the economics effect of policy, but it is far, far from being complete.
