As much as I enjoy homebrewing, I am pretty content at keeping it a hobby, unless after I graduate from business school, I would love to work in the business side of a microbrewery.
There seems to be a lot of common ground between homebrewers wanting to brew for a living and sound engineers wanting to make records for a living, which is something I used to dream about doing. I even went to school and graduated with a degree in recording arts only to find out, there are no jobs at studios for audio engineers and if you want a job doing it, you have to shell out tons of money to create your own studio. I see a lot of parallels between the two communities and those dreaming of quitting their day job to do what they love. There are however a lot more people working at a brewery than at a recording studio, so I would think the odds of getting your foot in the door are better
