Love shouldn't be about jealousy or anything like that. It should be about commitment and being able to trust that person. If you can't have that from the get-go, there's a problem.
If you're doing something new you've got to have a vision. You've got to have a perspective. You've got to have some north star you're aiming for, and you just believe somehow you'll get there, which kind of gets to the passion point.
