Alright, I'm going to keep this short and simple. A popular question amongst budding musicians, producers, beat makers, DJ's, and all other creative mammals is "How can I get anywhere with my music while I still have this 9-5 cubicle problem?"
A valid question, without a valid answer. There are many things one can do to free more time, and in turn have better means to be creative. I have struggled with holding jobs for as long as I can remember. It seems that after 3-6 months my boredom overpowers me to the point where I will either quit, or immediately start looking elsewhere for something "better" and more "satisfying" on a temporary basis.
A very important factor in balancing your day job and real job is to treat your art as a "job" with no exceptions. I dedicate a minimum of 1 hour per night, 6-10 hours on the weekends to work in the studio on whatever projects I currently have simmering. If you treat your art as a hobby then it will remain a hobby. If you treat your art as a job, and verbalize to your family and friends that this is a job than there is a better chance it eventually become exactly that.
One thing I am trying to do right now is make money from home via web publishing and internet marketing. Internet marketing takes minimal amount of money, and a butt-load of time, but once you have your niche markets and a handful of sites with passive and residual income you can eventually get to the point of only working a few hours a day, which in turn equals MORE TIME FOR MUSIC. I know, it seems far fetched but it really isn't. I recently met a chap my age from the states named Silvano who is trying to do the same thing. He is a hip hop fiend with a dream to make his living from home providing the world with relevant content relating to our mutual friends "boom" and "bap".
Since we share the same dream in a matter of speaking, we have formed a bond based on past experiences and future ideas. If you ever want to leave your 9-5 and chase a dream, you have better chances of surviving if you have a team or at least a handful of people with the same visions. Stay tuned as I will be getting more specific with certain steps individuals can take to free up more time. 4 Hour Work Week???? Thats coming later!
