I'm Having Trouble Picking a Field/Specification in IT

I've been on here a few times a while back, but I was never really serious. I ended up doing something unrelated to IT, but my love of the field has brought me back, and this time I really am serious about breaking into the field. I somewhat recently graduated college with a Liberal Arts degree(don't get me started on the waste of time and money), and that is obviously not helping me get into the computer field. What I hope will, though, is the fact that I've been working with computers as a hobby for over 10 years now. I just don't have any idea as to which fields are the most "open." As in, where is there room to get in? My knowledge is fairly varied, but I have been using Linux exclusively for around 7 years. I know quite a bit about just about every major distro, and have set up plenty of home and small servers. Would getting Linux certs be a good path? What about programming? I've done some Python and Java, and I do like that as well. I am by no means a master, but I'm willing to work at it. I've always been interested in security as well. I don't really have any experience there except for basic anti-virus/securing server knowledge, but it seems interesting. Of the things that I mentioned, is there something that stands out as a real opportunity? I'm willing to invest the time(not working right now) and some money to get to where I need to be. Thank you.

Apply anyway. Worse thing they can say is no.
Why not start with RHCSA? RHCE is an expensive test if I remember right.
RHCSA isn't and is like the CCNA of Red-Hat.
Then try to get a job with that maybe? Save some money, get some income, then go forward.
There are websites that connect developers and customers for short-term, simple engagements. This would be a great way to help boost your resume and give you more to talk about in the interview process. Here's a website that list the websites I'm talking about, however if someone has personal experience with one of these feel free to chime in

If you like Linux and programing, try doing web development and administration. It's really easy to get into web development; start by making websites for friends and/or small businesses for free (or cheap), and use that as a profile for bigger or full time jobs.
