Amen.<p>I think the reason people are afraid of sharing is that very few people practice continuous learning. They keep using what they learned 5, 10, 20 years ago, therefore - to their mind - if they share it, they are left with nothing.<p>I don&#x27;t mind sharing as I read like crazy, learn new things all the time, and improve my way of doings things so that I do and understand things much better than I did 5 years ago.
