Wise words from one of my favorite people. I regard constraints as a gift, and a tool. So I give you THIS:
Something made for people that think constraints are limitations. For them, I hope this points the way to freedom.
Something that is made for people who ask me, “tell me one of your secrets”. For them, I give one of the most important.
Something that is a powerful tool for anybody who needs to ship anything. For them, a potential differentiation between CONSTRAINT, and LIMIT.
