I've had many great ideas be kept on the back burner for years, while I worked to pay bills. I kept two day jobs to pay rent and eat, barely. I worked on the computer at night.
When I was in college I worked a day job, and I went to fullsail. Yeah.. The 24/7 school. Class on sunday at 4am.
In my first job I worked side contracts and consulted. I shared my knowledge. I also explored the new technologies and learned more. Don't ever stop your education.
Nothing ever turned fruitful, except my failures. Every failure I learned something from and moved on. I was fired from that first job on Christmas day because I wasn't working and my boss overwrote a production file before she got my changes. Thought I didn't do the work. You're lucky. You have GIT.
I worked from myself and taught myself project management and the skills to run my own business. I also started a family and added more bills. You have to play the waiting game and most importantly you have to try. Do not expect things to be easy. Do not assume people are on your side. Do not be afraid to lose sleep and work all night to prove your worth.
