I have had MANY hobbies. Here's the way most of them got started...my two grown sons get into a sport or hobby and I jump in just to keep doing something with them. By the time I join in, they move on to something else A couple of these hobbies were roller blading and mountain biking, which I still occasionally do.

Of course, a few hobbies I started on my own including ham radio, RC planes, golf, tennis, running, sailing, target shooting, and lately, electronic projects (currently Arduino).

My trumpet playing is much more than a hobby since I retired from being a professional engineer specializing in robotics and industrial automation to be a pro musician. I'm now officially a staving musician It's a good thing I don't have to make much money doing this. Still, music is a passion and I'm blessed to be able to do it
