My younger cousin was in his first year of college, and he told me he wanted to make video games. I told him about how hard the industry is on developers, and encouraged him to look into other careers. He eventually changed his mind and picked something else (something programming related, I forget what exactly).

He's a really bright and creative guy, and we'll never know what awesome game he could have helped make, if I hadn't talked him out of it. So it can be hard to see what we're missing sometimes.
