If your ultimate desire is to have a career as a professional pilot, I think the advice of “get a real job and fly privately on the side for fun” usually isn’t sufficient enough to quell that desire.
I personally think the motivations, achievements and fufillments gained through professional flying aren’t the ones that will be solely satisfied via private flying. And vice versa, there are some who will not be satisfied as professional pilots and would be better suited to restricting their flying to private aviation only.
It’s your task to discover if it’s professional or private aviation that you aspire to, and if it is a career as a professional that you are attracted to then just limiting your goals to private aviation will leave you unsatisfied.
I’m not going to talk you out of being a pilot, if you discover that it is your desire to be a professional pilot then go for it.
