I find it hard to work or do business with close friends, whenever there is a problem or discussion I worry that the relationship will be damaged. Separating business and friendship is hard.
If you are friends though shouldn't you be able to work through some really hard problems together and go through the ups and downs as a team? I find that friendship is an added bonus that helps you push through tough challenges that would otherwise make you want to quit. You can't let your friends down when the going gets tough...
