I am literally sacrificing every part of my life right now to get my mechanical engineering degree.

My plans with that engineering degree is to build a dubstep studio.

So now i eat, sleep, and breath calculus so that i can make music in the future.

Where i come from, i know alot of world renown musicians who have a day job.

Unless you have other obligations that need more financial priorities, you can work with your job to get the schedule you want.

But outside of that, you know what you gotta do man.

Or, consider activities that you are doing instead of making music. And i know it's a process and you need to be of right mind and body to do it, but you could be not doing it because of something else.

When i was working 12-14 hrs a day as a catering chef, i would just come home and smoke pot. Some times on my days off i'd get to making music, but it was mostly filled with smoking pot and playing video games. So those long days/work schedule really pays a toll on you.

Just make sure you do the work for the time being, and try to take every opportunity you can to make music. Even if it's ONE LITTLE SOUND or eq nudge, you've made progress.

Some times all we have is the small victories, just take em while you can.

I have a full-time, stable job that has nothing to do with music and isn't entirely "fulfilling" either.

But I once heard a good thing about having a job - you have the ability to say "no".  Meaning: when you don't have a job, you sort of need to take whatever comes your way if you want to live, eat, etc. But by having a stable job, you can evaluate your different opportunities and pick the best one for you from a place of leverage, not desperation.

So - sure, my job has nothing to do with music and it sounds wonderful for me to get paid what I'm getting paid now for doing musik stuff...but that's not easy to come by.

I'm working through this "job vs. passion" thing myself..

The ideal vision I think would be to have a social life filled with other producers. The thing that makes it hard is that most of my interests lie in music composition/production so when I try to hit up a conversation with someone it's not like I can say "Dude! I was messing around with bus compression the other day and realized that if I set a fast attack it really smooths out the transients!"

People will instead just look at me like "wtf..." 

As far as the job vs music thing you probably shouldn't quit your job until you're making enough income off of music to afford your basic expenses. Just my opinion though. Nothing's really set in stone.
