Practice! Nothing is better than practicing. The more you try, the higher the chance of succeeding. Pixel something. Even if its bad, post it on the WIP section and be ready to take criticism, as it will help you a lot. Some people might seem harsh, but all they're trying to do is to show you what you did wrong so you can improve.
So, practice a lot, and good luck. [:

Reading tons of tutorials won't improve your skills, only teach you theory.

Read a few introductory tutorials, then try what you learned by drawing something.
Realize that you're a beginner, so choose something easy and feasible. Don't try to draw realistically, that's hard, unless you already know about anatomy, perspective, shading, color etc... , and prefer stylistic approach, it's easier. For example draw a cute monster, or a cartoon scene.

Also don't draw thinking that  it is your next masterpiece. Just let yourself go, and enjoy the process of actually drawing. Learn to draw not only for the final result, but also for the pleasure of drawing.

To push you up, set quality targets for yourself: choose a piece you really like, from a game or another artist, study it, copy it (giving credit to the original author of course), take inspiration from it. Train yourself to see what makes their work look good, and what is missing in yours.

Once you feel more confident, you can go back to more tutorials, since you'll understand better what they teach you, and apply it in your work.
