+1 for the video. My main takeaway from it was don't assume that you and your co-founder are on the same wavelength - write down explicitly what you are agreeing on, and be concrete with figures e.g. "I'm willing to work 8 hours per day, 6 days per week", or "I'm happy to consider this successful if I make $100,000/year" etc
