Indierawk, did have a point though. Even if he did attempt to point it out while being an ass.
Practice. Practice. Practice. It's the only way to get better. That being said, go to the store and buy a shitload of notebooks, and pens. Fuck pencils. Seriously. My art didn't start improving until I started using strictly pen. Knowing you can't erase makes you more aware of your lines.
Draw all the time. Every chance you have draw.
If you can't figure out what to draw, draw whatever is around you. If you're completely out of ideas and bored with drawing whats around you, try to change it up. Draw only the negative space in a still life, alternatively draw only the positive space. Do a continuous line drawing. Look up a random genre of art and draw something for it. Draw something with your eyes closed. Draw an objects while looking only at it and never at your paper. Do timed drawings. draw for 5 minutes and see where it gets you. Draw basic shapes on your paper, and then make something else from them. Try copying famous works. Go to your museum, and draw some of the art there, or even some of the other visitors. Draw using graphs, and slowly work away from them.
I went to art school from preschool to 11th grade. Off the top of my head those were some pretty basic learning techniques. I took maybe one drawing class, but we had to draw a lot in my printmaking class, too. Basically, if you practice every single day, your get better.
