Insanity: doing the same thing over and over again and expecting different results.Albert Einstein

There are two things a person should never be angry at, what they can help, and what they cannot.Plato

I recommend the book Pragmatic Programmer

You can buy a person's hand, but you can't buy his heart. His heart is where his enthusiasm, his loyalty is. You can buy his back, but you can't buy his brain. That's where his creativity is, his ingenuity, his resourcefulness. Stephen R. Covey
