Me and some of my friends went on a joint venture last night. It was awesome.
Seriously though, a joint venture is just that. Some of them will be time wasters, some will not.
This is like asking if it is a good idea to go on a date? I mean, is she hot? Got Money? Ugly? Dumb? If she isn't your match, dont get involved. If she seems like a match, dont jump in bed with her on the first night.....
