> It really helps if you are just doing one thing. For example, Ruby on Rails development. Or iOS development. Or Wordpress plugin developer. This makes it a lot easier for people to remember you. When you do “everything” people will not immediately think of you when they have a specific problem.

Is there any way to market multiple skills and still succeed as a freelancer?

E.g., web development (RoR and Django), graphic design, and music production.

("A man can do all things if he will", can't he? Or are we technically unable to have such diverse skill set?)
