Interesting to hear about people "getting bored", given I have been at it less than a year. For me, the freshness is still in the discovery. There's SO much to learn, and I am happy to be learning and absorbing everything I can!!
I don't dismiss the fact that things can be weary in any "study" - heck, I have been involved in the pinball hobby for more than 10 years, and have done just about everything there is to do (from constructing cabinets, to restoration, to electronics repair, to giving public seminars, to competing), so I am bored with it as well.
I wish you the best, hope you can get out of the slump. Remember, making music is a GIFT and is virtually infinite from a creativity standpoint!!
