Thought: Why you should share your ideas

I have a lot of time for Derek Sivers' work, and recently came across this:

It reminds me a lot of what a mathematician friend of mine once said, "Once you understand something in mathematics, you think of it as trivial". So even the most complicated and only recently understood theorems are immediately relegated to the "trivial" - and so it seems to be with ideas you carry around in your own head.

His books are worth a read too. Full of lots of similar simply expressed wisdom.
