Welcome to the community!
I’m a recent convert to the field of UX myself, so I was where you are just a few months ago. You’ve come to the right place.
First thing you have to do is get to know what the field is all about. Watch videoes, read articles, read books. This community has plenty of good resources you can start with.
To start out light and fun, I recommend Steve Krug’s “Don’t Make Me Think” (Make sure to get the revisited version). It’s a short introduction to what UX is all about, and it is really, really charming. I even found myself exhaling hard out of my nose at some of the chapters.
Another good way to start out is to go through a video course. I payed a small fee ($14/month, I believe) for access to Lynda.com’s User Experience course. They start you out from scratch with the basic understanding of what UX is and what the different roles in UX are.
I also listen to podcasts while I drive. It makes me feel like I am optimizing, and it has really given me some invaluable knowledge. But pay attention to the road, please. I am fond of “UIE.fm” and the “UX Podcast”.
Oh, and be part of the community. Seriously. Don’t be afraid to throw questions around, there are plenty of people like us around, and the entire UX design community is really helpful. Join us on Slack, too. It’s the best place for questions that don’t need an entire forum post to explain.
