I hope this helps, as I have felt like you before...like everything, magic has it's dips on the love factor.
When I was in University, I was performing 4 nights a week doing walk around gigs, and private parties on top. The audiences would make me feel like A GOD some nights, others...and I quote, "one step above a mime". I was meeting so many people, that I was becoming very well known...and I hated it. People didn't take magic as serious as I did, they would EXPECT me to be bad, and I would always have to win them over. Some would even apolagize because they didn't think I would "be so good". I just started getting sick of hearing the same responses, and having to continuously climb the uphill battle of sharing something that people innately hated (magician in trouble effects are BUILT off this concept). It sucked, why does a juggler drop a ball...and people cheer him on...I find the wrong card and they are happy? Just to be followed up by finding the right one, and they are surprised, and happy still...but I felt like I had to win them over.
Anyhow, I talked to one of the well known magicians on this site, and expressed how burnt out in magic I was. He said - take 48 hours where you don't touch, look, or think of magic. Then, see if you miss it. I did. Then, he said - don't forget your job. We take ourselves too seriously, your job is to mess with people...go have fun with them. Give them an experience, and that experience is you. This helped, as I didn't care if people thought it was going to be good, or bad - I told them it was going to be good - and then did good magic. There weren't educated enough to make a decision before sampling, so I got thicker skin...and still laugh when someone says, "wow, I didn't think it was going to be that good" - when I work at a gourmet restaurant where the food is HIGH end - so the food is SUPERB, but they assume the entertainment will be mediocre? Always my advantage though.
I also spent time at conventions, the magic shop, or anywhere I can be around guys better than me - I instructed at Sorcerer's Summer Safarai, so it allowed me to spend time with many guys that are very skilled and instructed as well - this allowed me to watch...most times, I didn't do much magic there, I just wanted to observe, enjoy, be inspired. Instead of pushing MY stuff on people, I took a back seat and learnt.
Which leads me to this - people get bored of magic (and I can honestly say I don't anymore) when they forget to progress. We start to think, "Oh, I am good - I fool people consistently, and people tell me how geat I am". Really - go to a lecture of a really talented and well known magician. Remind yourself you have a LONG way to go. The thing with magic, is that NO matter how good you are, you have SO much room for growth.
NO disrespect, but I bet if I looked at the effects you do, and how you do them, I could spot MANY things for you to work on. It could be a more interesting, unique or engaging way to present an effect, it could be a move, it could be a handling. You could expand your magic to other props.
I would also say this - you said you have many hobbies that you can make money off of. I don't know what that has to do with anything - I hope that it does not mean you are the jack of trades, master of none. I hope it doesn't mean, I can make money without magic. I hope it doesn't mean that the only reason you do magic is because it pays and it was easy, because people in high school ate it up.
I would hope that you are just at a part where your brain, that we don't always listen to, is saying - DUDE, WAKE UP - you need to progress in magic, that is why you are sick of it. You need to challenge yourself to do more - not just learn a new trick - but to look at your magic on a deeper level - what are you REALLY offering people. PM me and we can chat more - but the magic cure is progression....always.
SO - what venues do you do magic? Have you read the book Strong Magic - that could really motivate you - pick up Designing Miracles while you are at it. If you have read those - take a look at your magic, does it look moveless, flawless, is it what you think magic should be?
If all else fails - like was told to me...put it down for 2 days, on the third day, think about what you hate about magic - on the 4th day - think about how you want to change that - then create, practice, trim the fat!
Hope that helps, really. We have all been there.
