I wash my hands religiously... like prolly 40-50 times some days. And, immediately after, I have to use a moisturizer on them.
I spend way too much on skin care products, supplements, and hair care. Way too much. I blame the beauty forums I frequent... >.>
I worry about my car when I can't watch her. My baby... When I take her to the track/events I get paro if I see people looking too closely.
When I start work on a new music track, I often completely disappear from outside life. Ignore my phone, etc. My friends bug me and get weird about it, lol.
I actually enjoy rewiring my entire studio when I get new gear. I plan it out with diagrams, mark cables/snakes accordingly, clean pots/faders/jacks while everything is unplugged, etc.... very meticulously. Usually takes a day or two before I actually get to use the new piece of equipment, lol. My back hates me for doing it, though... crawling around under the console, behind racks, etc. I can't wait to move so I can set up a new studio space. Only part I kinda dread is tuning the acoustics. Gets very frustrating, at times.
