If you like what you're doing, figure out how to make it work for you and don't stop trying. You only get what you settle for after all.
I've given lots of people the same advice, but over the years I've learned to drop the part about not giving up. Some of the biggest steps forward in my life have come after I realized it wasn't working and gave up on something.
When I was a teenager I wanted a big stereo in my car, something that would turn heads as I drove down the road. I couldn't afford any nice gear so I sat back on the forums and learned about car stereos, equipment, install techniques, sound theory, electrical theory and so on. This eventually turn into a desire to be an installer, I wanted to be the next Fishman or Mark Eldridge. When I was 21 I finally got a job in a shop, I worked my but off, learned a ton. A year later I was building the giant systems that could literally make you stop breathing. I was doing it man, living my dream, I even helped build a world record setting car.
But man did the customers suck. After three years of crap customers I was burned out on the industry, 10 years later I'm finally getting back into a hobby that once consumed my entire life. I let $3000 in speakers sit on the shelf at home for 10 years because the customers just beat the joy of it out of me. I'm finally building my first big system now. Though I'm much more mature now and won't be blasting it as I drive past your house
Next up was truck driving. I remember listening to all those trucking songs as a kid, I knew where every trucking song was in my parents LP collection. When the family took road trips I would track out progress on a map, I could proficiently read and navigate on a paper map before I entered middle school. By that time I had already been halfway across the country and back a few times. By the time I got my first driving job I'd already been to 36 states.
I drove for about 10 years, I just barely hit the million mile mark. There were tough times, but the good days far outweighed the bad. On the first Monday of 2010 I woke up with less than $2 to my name, but I still loved the job. But the problem with being on the road 300+ days a year is that it becomes your life. Before you know it, you haven't seem your friends or family in months. And try dating when it'll be a month between your first and second date, good luck with that!
I did eventually meet a girl, and we drove together for about 6 months. The problems is that we were stuck with each other 24/7 or we could be apart for long periods of time, neither would make us both happy. So a few months ago we both gave up our driving jobs and decided to start from scratch. After 10 years, I still love driving, but I hate the industry for how it chews people up and spits them out. Your choice is trucking, or a life. It's very hard to find a comfortable middle ground.
Back when I was getting out of car audio a friend asked me, "What are you doing Saturday? Wanna make some extra cash?" I'm not one to turn down an adventure, so I said sure and worked as a stagehand for a day. It was tough work, but a bunch of fun. I did this on an occasional weekend and enjoyed it. I gave it up when I went long haul driving.
A few months ago I picked it back up and decided to see if I could make a full-time job out of it. I'm having a ton of fun, working hard and even got my first touring gig. My body is sore as hell after working multiple 20+ hour days in a row. But on days like today I get to just saunter around the house and tinker with things like my car. Or I wander around town with my camera looking for photos to make. Will I do this job for the rest of my life? My track record says no, but it's good for now.
What I'm trying to say with all this rambling is yes, go for it! Do the best you can, get yourself noticed in the industry by doing GREAT work. But if it doesn't turn out to be what you think it is, and it's ruining the "hobby" for you, then there is no shame in quitting. Maybe it'll work out and you'll do it the rest of your life, but maybe there is a better opportunity waiting for you when you decide to move on. Either way, you'll be far better of if you try it than if you just dream about it.
That said, my current hobbies are car stereos, photography and exploring my new hometown.
