If the work isn't so much and doesn't require a co-partner, then i would like to work on my own. I like doing things my own way and i really don't like the idea of involving someone else in my business.
Personally this is exactly the same way I see it because it is the nature of the work you are doing that is going to determine if you need a co-worker to help you to carry out the task successfully otherwise it is not needed.
