Never step in anything soft. 12 Shit really does happen. Warranty and guarantee clauses are voided by payment of the invoice. Nothing is quite so annoying as to have someone go right on talking when you're interrupting. Those who think that they know everything are a constant irritation to those of us who do.
Nothing is as easy as it looks.
If several things can go wrong, then that which costs the most will go wrong. If everything seems to be going well, then something has been overlooked. Nothing can be made foolproof, because fools are so ingenious. A computer can make as many mistakes in two seconds as twenty men working twenty years can make. Life is a series of circumstances beyond your control.
