The fun/non-fun engine of two times keeps working fine for me in regard to music production. In fact I've found that any deviation from its paradigm is fictitious, it catches with you later.
The line between fun and non-fun is not only subjective but also highly fluctuating (like: day to day fluctuating), so sometimes you yield to pressures of the moment and say: "OK, this task is not really fun, but it's almost fun, or will quickly lead to fun..." This stretch is part of the production strategy, one more tool in your arsenal, but in the latest times I've overused it; becoming more and more obsessed with set deadlines and results (or to put the emphasis somewhere else, too sad for the sluggishness of the whole thing), little by little I've been slipping without noticing it into full time non-fun.
This excess has finally caught up with me. Luckily, the counterbalance in this case is a happy one, because it has lead me to internal and external research and I've come across a new "vein" of fun that I'm now exploring, and now I'm going to be making music only for my pure personal gratification for some time. In other occasions, however, the results of a strain of this kind can be not so happy, they can lead to demoralization and even lead you to store the instruments and "forget about the whole damn thing"...
I guess the analogy of application here is the kid who is learning to walk. He takes two steps, falls down. Takes one more step, he's sure now he's got it, he falls again. Of course he never stops standing up whenever he falls down. There's too much to learn up there, and besides he's had enough of crawling already.
I will surely forget again about the importance of having fun, and I also for sure will keep trying every time. When I come to think of it, having fun is very connatural to making good music, it's a deal maker or breaker, it blatantly shows in the results. A guy will never go to a chair manufacturer and say "hey dude, I want to complain, you had no fun the day you were making my chair, you just followed the procedure, went through the movements..." No mood signs can be inferred from the finished product. However, when a musician is not having fun, when he just "goes through the movements", you bet it shows, and it's not precisely a pretty sight...
I have a guitar and I'm gonna use it
