I make a decent amount through the various freelancing platforms; enough to live if I work hard enough. I've always done writing, but some research has shown me that there are much more lucrative skills for online freelancing. I've started to do some programming, and it definitely yields more profitability. Of course, sales are closely related to most freelance writing jobs, but there are other categories of freelancing too! What are your experiences? Which freelancing skills have you found most lucrative?
