for example, you can watch on Youtube various videos of someone renovating or building a house, you will probably learn many things (even some wrong) but that won't make you an architect, right?
But it is not necessary to leave a profession for another, we have some people who have 2-3 degrees in different fields and they killed it anytime they activate any of them. You can be a Medical doctor and still be an economist, you can be an evangelist and still be an economist, you can be a philanthropist and still be an economist, you can also be a musician, a fashionista and still be an economist. Although, anyone can be professional in all but there is one they always dedicate time to and like the most.
