Santa Claus doesn’t mind if people don’t believe in him. It’s enough that he believes in himself. Same goes for game developers I think.
Anyone looking for a good book, should check out the book behind Door 3. In my not so humble opinion, that book is so made for all creative wanna-be developers and people who want to find a way to make game dev. Or just people who like to get a different view on things (I’m on page 15 and really enjoying reading it).
