You may be disappointed if you fail, but you are doomed if you don't try.
Always forgive, but never forget, else you will be a prisoner of your own hatred, and doomed to repeat your mistakes forever.
How could I have been so ignorant? she thinks. So stupid, so unseeing, so given over to carelessness. But without such ignorance, such carelessness, how could we live? If you knew what was going to happen, if you knew everything that was going to happen next—if you knew in advance the consequences of your own actions—you'd be doomed. You'd be as ruined as God. You'd be a stone. You'd never eat or drink or laugh or get out of bed in the morning. You'd never love anyone, ever again. You'd never dare to.
I am a design chauvinist. I believe that good design is magical and not to be lightly tinkered with. The difference between a great design and a lousy one is in the meshing of the thousand details that either fit or don't, and the spirit of the passionate intellect that has tied them together, or tried. That's why programming-- or buying software-- on the basis of "lists of features" is a doomed and misguided effort. The features can be thrown together, as in a garbage can, or carefully laid together and interwoven in elegant unification, as in APL, or the Forth language, or the game of chess.
