I think this is a great question.As someone approaching 62 and about to be celebrate 40 tears of marriage.[Freudian slip] thats:'years'Here is my take:if you have enough money, kids are grown up and the missus is supportive forget balance and do the thing you love.I read somewhere in a survey, elderly folks regretted not taking more chances.I was a pro singer,drummer songwriter for 20 years,went from near stardom to a hotel residency in England[drove me nuts]I have been out of the business for the last 18 yrs and run a lawn service ,sole proprieter,bust my derrier!I certainly dont have enough stashed away for retirement but have started gigging again[on keyboards]and have played about 27 gigs since in the last few months[just seniors for now]My playing seriously sucks ,I struggle with PA and digital pianos,but when I sing and I can tell its beginning to click musically,even the audience notices it .It reminds me of the passion I originally had all those years ago.My 'true north' so to speak.I intend to end up playing some sort of solo jazz and funk set and do private parties,corporate meet and greet etc and dump the lawn business and sing and play till I drop.I also intend on writing again and have put together a little'studio'and will look to get published,again.If you have this in you you have to express it.We all know the entertainment biz sucks and artists are in the main not given their due,you are an artist remember,tip the balance in the right direction.Head North!

I think it's the predecessor to "Early to bed,early to rise" yada,yada,yada.

Use your day jobs to finance your creative endeavours and be VERY thankful that you're in a position to do so.
If ANYONE paid me what they're paying you,I don't know if I could stand it! *LOL*
