A while back Garr Reynolds posted an article about the “Tips for creative success from Pixar“.
An interesting quote from this article is the following statement :
Accept every offer. Don’t judge it, you’ll stop it. It becomes a dead end if you judge it, but unlimited possibilities if you go with it.
To be honest, when being a junior engineer, you accept a lot more tasks without judging it. It’s a zen saying that one must approach things with the child’s mind. So approach it without judgement. Creativity & openness is something we have to maintain, as it’s something we loss over the year due to our prejudices & the context we’re accustomed too.
