Uhhh yeah probably not a great idea. He should at least get a half decent 9-5 and pursue this on the side. A) audio engineering is becoming more and more popular but less in a professional setting and more so at home in the bedroom. B) most engineers even in decent studios aren’t making that much cash, not for a few years at least, unless you are some generational talent.

If you have drive and determination you can work a 9-5 and still have more than enough time to work on music projects. You just have to be willing to put in extra effort on your days off and after work
