Thanks for the plug Trevor! Yeah, that's me too. My graphic design and web design stuff is "on the side". I am a computer science geek from way back and since then, software product management with a love for Photoshop and Illustrator. I can't offer any advice from a professional graphic designer aspect as that is not really my profession, but I found that you can learn tons from tutorials to see if you like programs like Photoshop. You can watch videos on Lynda.com or those that come with book, or you can read books if they don't put you to sleep (mine or purely for reference). Heck, you can even learn stuff on these user forums!
Clearly being able to do freehand drawings and sketches (and digital sketching) and having a background in color theory and deisgn are pretty important, too.
I personally wanted to have some updated coursework, so I took all the digital media ,color theory, design, web design,web programming, Photoshop, Illustrator, social media, marketing, and other classes related to graphic design and digitial media that the local colleges and artist workshops offered. I made a lot of new friends and business connections. I also did some web designs, logos, posters, and other advertising stuff for people who heard about me through friends. Volunteer work is another great way to show off your talents and get referrals from people. Doing a few projects for some local clients will give you an idea if it is what you want to do for a career or not.
Many colleges in the US (2 year and 4 year schools) have online studying options...From the local Junior college to places like SCAD in Georgia.(and many more). There are also many colleges that offer art degrees online only.
Jamaine- It is great you are driven to go do something...that will get you far. Go learn and go for it.
