I do my best to choose carefully. If I don’t feel that collaboration is going to happen, I say no. Think about it. These projects can involve a five-to-seven-year partnership. If you don’t feel comfortable with someone, you can’t get rid of them. I just walked away from a job for that reason. Every one of these projects is an emotional investment, like falling in love.
