Why do incompetent people still opt for freelancing?

[Btaliat]

Are you always wondering why we still have incompetent freelancers despite the fact they have lesser chances of getting employed by any client. Majority of them will still have themselves writing proposals and vying for tasks even when they know that they are not competent at all. I don't know what always bring about such an audacity? What do you think? Why do you think we still have people that are not competent in freelancing?
