Why do most freelancers fail to succeed?
It depends on them. I think most freelancers fail due to lack of grip on their skill. I started freelancing 4 months ago and I think this is the reason. It varies from person to person. I may be wrong so coming points and reasons are welcome.
Some fails for the lack of work skill, some fails for poor communication skill, some fails for lack of patience. If someone have all these, he must succeed.
The same reasons why most new businesses fail, I guess.
