Is your day job professional knowledge work that allows you to build up the experience/career capital that leads to higher pay, more autonomy, etc.? If so, maybe keep flying for fun. Airline pilots are industrial machine operators. It's a specialized, non-transferrable skill. And your career progress isn't portable due to seniority. Sure, lateral moves are possible in 91/135, but there's also a lot of uncertainty in that world, so you'll be making quite a few lateral moves over the course of your career. That's not to say that the airlines are sure thing either. Pilots often declare a golden era of pilot hiring only to be thwarted by the the next economic downturn. In those situations, one can find themselves without the tools to make a good living. Consider all the laid off euro pilots becoming bus drivers, Amazon deliverers, etc. during COVID.
If you're young and your current job is not professional level knowledge work, well, then maybe you could become a pilot. But do so with the knowledge that you're choosing something over other lucrative and in-demand careers that offer the opportunity for more professional treatment, flexibility, home time and money.
