I felt called to work in acute psychiatry- in psych hospitals and on locked wards and forensic wards.
Is that "challenging" enough for you?
Of course it is. It's doing good for other people.
It's not jacking in a job for something that isn't gonna happen. Most musicians have proper jobs. A few make enough to support themselves - but unless this bloke is already writing, recording, has sold in the thousands and has an established fan base, he is not one of those.
The Christian Music sector is an immensely powerful and well established commercial structure - I know people who make a living in it - and they haven't suddenly decided age 37 to drop everything, they've got degrees in Music, they've been performing as soloists since childhood, they've got contacts, experience coming out of their ears and usually pay the bills through such things as running internationally well known choirs, giving singing lessons in schools, running courses and shows outside schools, working as Youth Mentors in PRUs, running the sound at large churches and festivals, composing for well known performers who they have nurtured and supported to develop their own careers over the last twenty years, depping in West End shows, have built their own recording studios and recorded/mixed/produced tracks for others. It's not 'turn up to an X factor audition and talk about Jesus calling you to lay down your spreadsheets, abandon the Year End procedures and your VAT Returns and The Wife will provide'.
Quite frankly, he hasn't got the essential things that are necessary for the marketing. Coldly, but truthfully, he needs children for that - lots of them - because then he can have social media with shining faced cherubs, the big house, the aspirational lifestyle that will get followers, views, likes and clicks.
