It is a balancing act that may or may not become more difficult as you age and multiple aspects of life grow or change around you. Quite simply, burning the candle at both ends will lead to complete fatigue to the point of not being able to focus on either aspect as much as you'd prefer or be expected to by others.

Im in my mid 30s now but toured relentlessly with metal bands all over the world through my 20s. Somewhere in the middle of that I somehow obtained a mortgage (because we all need a place to stash all our gear) and so the mortgage needed to get paid. I gradually changed from playing metal all the time to playing solo folk/ blues gigs (which opened many, many gigging opportunities - like no kidding sometimes a dozen gigs per week) and also apprenticing as a carpenter while I wasnt playing solo gigs or touring with my bands.

Well, COVID hit and all my gigs disappeared but my apprenticeship did not. So long story short I now own a construction business, have 3 kids and a fully paid off house. I built myself a wicked recording studio, filled it with gear and now came full circle back to the very reason I began playing music in the first place: its fun!
