The document contains four quotes about learning from experience, software development, and project constraints. The quotes advise that it is painful not to learn from past mistakes, software programs are never truly finished but work stops, and fast, good, and cheap project attributes can only have two but not all three. Staying in bed to avoid debugging on Monday is also suggested.

1. “There is only one thing more painful than learning from experience and that is not learning from experience.” “You never finish a program, you just stop working on it.” “ “Fast, good, cheap: pick any two.” “Sometimes it pays to stay in bed on Monday, rather than spending the rest of the week debugging Monday's code.”
