i totally know where you're coming from, in the aspect of multiple interests. i play guitar for my college's jazz band, i play classical/flamenco styles because i love 'em, i obviously get down and dirty with the rock, metal/metalcore, and i have a soft spot for indie music after all that. sometimes its just overwhelming. i have different days where i work on different things. today, i've been doing jazz licks on a light-stringed acoustic so when i pick up my electric, i'm blazing up and down it. my biggest peice of advice would be to play everything you play on an electric on an acoustic. within reason, of course...no one is expecting you to pull off sweet bends and heavy vibratos on an acoustic. but i would definitely practice scales and licks on the acoustic before you even touch the electric in the morning. it took me a long time to find an acoustic guitar that played like an electric guitar, and i just recently bought mine. since then, its made dramatic improvements on my practice regimen.

but like i said, i would just try to get heavilly into a particular style of music for an hour or so, and switch off the next day or whatever. i spend 2/3 of my time writing songs and singing/songwriting on the guitar, and probably only 1/3 of my time working over licks and shredding up the guitar neck and such. thats just me, though. i know guys that wouldnt even think about not doing warmups every day.
