Seriously great advice above. Especially the bit about drawing everyday. You have no idea how far that will get you. Everyone can be an artist, the difference is generally only the amount of time invested. I went years without drawing, and now have to get back up to speed for where I once was. Just keep on it. It's hard to teach or give proper lessons until you have a general idea of the style you are naturally skilled at conceptualizing. The way you perceive the world is unique, and it's best to do art that appeals to the way you see things, rather than learning someone else's. For instance, my vision is REALLY bad... so I focus on shapes and shading. Well, those are my strongest areas... although I do have an obsessive amount of detail as well, it generally isn't noticed as much as ton and geometry in my work.
I'd be happy to try to help, but honestly, the process of self discovery is more powerful than technical training. You generally seek training to refine your weak areas after you have identified your strengths.
Don't down talk yourself either, you DO have strengths. I promise. Just find out what they are and practice them to death. The rest comes with time. It's always best to start with what you are already good at.
Some of my advice will not be accepted by everyone, but hey, art is all about perception and interpretation. The process isn't something set in stone.
