well i dj as well and that's what pays the bills, which also means i don't have to churn out masses of tunes. i've known producers who just produce music and nothing else and it IS possible to live like this but the problems come when you're trying to balance creativity with business. i think it's very, very hard for producers in techno - you must have something else in my eyes. and if that's something else to do with music then that's the perfect senario.
one things for sure, you have to have a get up and go mind, as well as a good amount of business sense if you're ever going to make it as a producer. don't think it's an easy path cause it definitely 100% isnt!!! years of going without, couple with knockback after setback after shit and even more shit. i don't think i've ever been 100% happy with any tune we've ever done and the rest of the time is spent arguing in your own head about whether a couple of db's off 50 Hz really is making a blind bit of difference ;)
