I have been on both sides of this relationship in life. As much as I love learning new things, I also love sharing them with those who wish to learn as well.
And this relationship is important as it feeds the hunger to learn more so that you can share more!
I have learned many things in life, some useful, some just entertaining. Over time, you learn so much that you forget many of your accumulated bits of wisdom. And it is not until someone starts picking through your brain, that you remember half the stuff you have stored away in boxes in the corners of your mind.
Which begs the questions, can you have a yard sale for all your excess life lessons? What is a memory worth on E-bay?
