Good game designer advice

I was talking to a game designer recently about what it was like designing games, and how to get into the profession. He gave me a good tip:

This is my personal belief and not all designers may share this view. Your happiness, success, and satisfaction as a game designer is directly proportional to how many smiles-per-minute your game generates from players -C.D.

Since I’m smile-y by nature, I really like the idea of spreading the smiles. ^_^
