I've ALWAYS gone in cycles where I'll get into something (a sport, hobby, work-related stuff, games, being a vidiot in front of the boob-tube, heck - even what foods I like to eat) and, for awhile, I'm gung-ho and all-consumed while almost everything else gets put on hold. Then some internal switch turns that particular subject off and on to a back burner it goes only to be replaced with something else.
After 50 years I've realized that this is just how I am and it's really not possible for me to fully change to fit a "normal" person's type of schedule. I did well in school, but would have absolutely KILLED every subject if I could completely immerse myself in only one or two subjects for awhile and then switched to others instead of trying a buffet of several every day.
To illustrate this using my studio as an example, when I'm in that zone, I'm into it day and night; buying gear, learning, playing, writing, recording, mixing, refining, etc., etc. Then, without warning, I leave everything and can go
months without even picking up an unplugged guitar to noodle around the house with.
Since I have some extremely varied interests, and have always realized that the best way to get the most out of an activity is to really learn it and use the best equipment, this can get stupidly expensive and require LOTS of storage space that others absolutely don't understand! "If you're not using it, then why don't you just get rid of it?" "Because as soon as that switch turns back on I will definitely be using ALL of it again!"
I've given up trying to change who I am, but it's definitely hard on the pocket book and relationships! LOL.
