Etching patterns into your mind

From Playboy’s interview with Steve Jobs:

“Playboy: Why is the computer field dominated people so young? The average age of Apple employees is 29.

Jobs: It’s often the same with any new, revolutionary thing. People get stuck as they get older. Our minds are sort of electrochemical computers. Your thoughts construct patterns like scaffolding in your mind. You are really etching chemical patterns. In most cases, people get stuck in those patterns, just like grooves in a record, and they never get out of them. It’s a rare person who etches grooves that are other than a specific way of looking at things, a specific way of questioning things. It’s rare that you see an artist in his 30s or 40s able to really contribute something amazing. Of course, there are some people who are innately curious, forever little kids in their awe of life, but they’re rare.”

We have to actively work on etching effective patterns. And we can never stop.
