As a young and very "green" developer, I have to agree. The biggest thing I've learned is:

Someone else has probably already solved this problem 30 years ago, and they solved it in O(n) time.

However, that's never a bad thing, or it shouldn't be.

I think an unwillingness to look backwards is a sign of an unhealthy level of pride, and I'll freely admit that it's something I struggle with. However, I believe many (most!) developers would also benefit from trying to get past one's ego.
