The analogy on oracle join and the behavior of immediate superior by Tom was really cool.
See this.

Your boss could micromanage you and tell you bit by bit what to do. And a lot of it would seem repetitive to you. By the time you were done - you would see that there was a really efficient way to accomplish what you just did in a fraction of the time - HAD YOU BEEN TOLD what the goal was, not how to do it.

Really Cool & I felt it was right !
