I have struggled with this issue my entire life. I have way to many hobbies and it is difficult to become proficient and obtain all of the gear that you need for each one. My biggest hobby the past 5 years has been bowfishing. We got into tournaments big and I literally spent 2 nights a week working on the boat, 1 to 2 nights a week scouting the next lake, time studying maps and lake topography, and 1 night a week tournament fishing. We hit our peak last year and finished first in the state by a large margin. It had become so competitive and it involved so much work that this year I have been out less than 5 times total. It had turned into a job and it was something that I felt like I had to do. This year when the tournaments started I didn't have the desire to put in all the effort to compete but I felt like I "had" to go. I went out to a few competitions and decided that it would be best for me to just give it a break.
I guess the moral of my rambling is that you should always make sure that your hobby is just for fun and make sure that it stays that way. Don't do something so much that you get burned out and it looses its fun. For me personally I have to retain enough hobbies that I don't get bored with one, however, too many gets overwhelming. Currently I like to reload, shoot guns, work on my house/property, ride atv's, ride streetbikes, camp, fish, hunt, hangout on the lake, rock climb, kayak, building and flying large remote control airplanes, or basically any other outdoor activities. I recently got into waterfowl hunting which is a huge undertaking in itself to obtain all of the gear and knowledge. I try to not get into any new hobbies these days unless it is something that I think I would really enjoy for a long time. Maybe one day I will drop half of these hobbies that I have so that I can obtain my pilots license.....That is one thing I have wanted to do since I was old enough to know what an airplane was.
