You and a business partner are inseparable on monday, largely because you're about to throw a lot of money behind something and you can't stop talking about it. On tuesday and wednesday, when you tell someone about your project, they might not have the same view about it that you do, which may be frustrating. But this devil's advocate can also provide some valuable points you should think about. On thursday and friday, take a risk. If you've been sweating over closing the deal, it's time to take the plunge. Overcome tension by cracking a joke. And when all is said and done, go out and get a milk shake.
