"It is impossible to unsign a contract, so do all your thinking before you sign."
"Warren Buffett has learned that once you sign, the deal is done. You can't go back and rethink whether it was a good deal or a bad one. So do all your thinking before you sign. This is easier said than done, for once that paper is shoved under your nose, sound reasoning often flies out the window in the name of getting the deal done. Before signing a contract, imagine all the things that could go wrong-because they often do go wrong. The road of good intentions is paved with what were foreseeable troubles. Thinking long and hard before you take the leap will save you from having to think long and hard about all the trouble you just signed on for."
