Making games is definitely not like a part-time job. Money is not guaranteed and loads of hours get poured into your creations. By quitting my job (hopefully permanently) and taking on focused indie development, I basically did a leap of faith. I believe in myself enough to risk my college education and financial safety on the games I make and the blog I write on.
I'm hoping that my games get reviewed and sales pick up soon. My college tuition problem is getting worse and I admit to having a moment of serious self-doubt a few days back. With renewed vigor I look to the future and I look at myself. Who I've become since I first learned Java. I think I have what it takes. I know indie development is worth the risk.
