Since programmers create programs out of nothing, imagination is our only limitation. Thus, in the world of programming, the hero is the one who has great vision. Paul Graham is one of our contemporary heroes. He has the ability to embrace the vision, and to express it plainly. His works are my favorites, especially the ones describing language design. He explains secrets of programming, languages, and human nature that can only be learned from the hacker experience. This book shows you his great vision, and tells you the truth about the nature of hacking. -- Yukihiro "Matz" Matsumoto, creator of Ruby

Show, don't tell. -- unknown

You may be disappointed if you fail, but you are doomed if you don't try. –Beverly Sills

Few things can help an individual more than to place responsibility on him, and to let him know that you trust him. –Booker T. Washington

It's your place in the world; it's your life. Go on and do all you can with it, and make it the life you want to live. –Mae Jemison

Don’t let what you cannot do interfere with what you can do. ~John R. Wooden
