There’s nothing wrong with following your passion if that makes you happy. However, if that is to the detriment of your family then it’s something that people do need to think about.
People who are musicians do make some money at it, but the reality is that it’s often sporadic and unreliable,and the absolute truth is that this isn’t about who made it at what age and so on. Given the numbers of musicians out there very, very few make it into the big time so it’s unlikely to happen for him that way, and if they’re aspiring to the big time there does need to come a point that one accepts they’re never going to be famous but that doesn’t stop them from doing what they’re doing.
I do absolutely think that musicians who are good enough at what they do should be out there gigging where possible if that’s what they want to do. But I also think that being a musician isn’t an excuse for not having an actual job which pays a monthly wage if you have a family at home.
I used to know someone who claimed to not have a job because he was a musician and that took up all of his time. Truth is he wanted to be a musician, made a bit of cash playing gigs some Saturday nights but was never going to make it into the big time or earn enough to make a career of it. But because he thought he was a musician that was all he did, while living on benefits.
If you’ve ever been to borough market you will discover that it’s full of out of work actors who are working on the stalls there while waiting for their next big break.... which rarely comes.....
Be an actor, artist, musician, whatever by all means, but as a supplemental not a mainstay because if you have a family your commitment should be to them first and foremost.
