I work a classic 9 to 5 type of steady, comfortable and financially rewarding job. I have also started my own indie game development studio that has nothing to do with my career.

As someone doing both, I can say that doing something you want to do, for nobody's sake but your own, is very fulfilling. It is also incredibly difficult and can leave you broke and disappointed, so choose carefully about when to go all-in.

Also, there is one surprising similarity between 9 to 5 careers and entrepreneurial ventures: success in either correlates very highly with how hard you work and your level of ambition to do well.

Passion and effort aren't things that the job can create for you. They're things you create for yourself.
