I've found that when it comes to freelancing, at least for me, the best way to make money and find jobs is to have a particular set of skills you can market. I've found my niche in video and photography and have been marketing those skills for a couple years now to some good success.
The interesting thing about video is that there are always smaller areas within in that I can hone more skills in. Right now, motion graphics is a growing field within in video, which deals a lot more with graphics and animation than traditional video, which I find fascinating. I was recently given an assignment to build a motion graphics package, and I found that I had a blast doing it! As a result, I'm interested in learning more animation, and I've enrolled myself in a graphic design course so that I can better understand Adobe Illustrator as well. It's exciting knowing that you're developing a new skill that you can market yourself with soon!
What about you? Do you have any newfound skills or niches you're working to improve on? And if so, how are you going about doing that?
