I’d say you should use two rules of thumb:
- Which of these do I love?
- Which of these can I use to serve others?
- Are any of these choices spiritually DETRIMENTAL to me? (If yes, cross them out RIGHT AWAY)
- Unknown as of yet
Here’s an example from my own case. I wanted to do video games since I was…6? 8? 10? Not sure of the exact age. It must’ve been when I beat Sonic 3 & Knuckles, and I saw some the credits at the end of the games. “Wow, people MAKE these things? I want to be one of them!”
As I grew, my spiritual maturity began to grow and started to manifest itself during senior year of high school. I still loved video games. I didn’t like the direction they were going, however. I saw that they were becoming excessively obscene. However, I still saw alot of potential for GOOD, inspirational (and morally clean) storytelling. I still wanted something to do with it.
I carried on this dream up to college, where I’m taking Computer Science. As time went on, however, it seemed like there was little hope for the industry. I’ve given up on games, but I still love CS. Not to say that I wouldn’t make one of my “dream games”. I just don’t want to be a tool of the industry.
To make a long story short, just use my guidelines, and you’ll be okay.
