This isn't true. Very few people are bad across the board -- find your strengths (as other commenters have said) and focus on those.
It's better to be excellent in one or two areas, especially ones your passionate about than solid across the board. If you suck at something and it's causing problems, that's a different story -- but don't get stuck on comparing yourself to others.
I wish I could downvote this comment. Please ignore it.
Quite a few people don't have enough skills to freelance. Either because they don't have that one skill in high demand, or they lack the drive to network and sell themselves. These people will just become miserable trying to make a living without a steady employer.
