I'm completely self-taught, beyond the odd high school art class that told me things I already knew.
Honestly, what helped me the most is looking at photos of things I wanted to know how to draw and started drawing pieces of it. Anatomical diagrams helped too, especially for hard-to-draw things like hands and feet. Learning physiology (the way you use a certain body part) is just as important as learning anatomy.
You draw it, look at the photo, look back at your drawing. If it's not the same, try to find out why and keep erasing. Even to this day, ninety percent of my pencil/tablet pen strokes get erased. That's just how it's gonna be. Don't give up just because you have to keep erasing!
Look at artists you like. Don't try to emulate their style exactly but try to parse out WHAT you like about their style and try to incorporate it into your own stuff. Maybe you like how they use colors, or maybe you like the way they draw eyes. Inspiration is great!
As for tutorials, I really, REALLY love shingworks' tuts. They can be found here!

It's so, so very easy to get discouraged when you feel like you're not 'there yet'. But don't give up! You'll never, ever be 'there yet' because as your ability is honed, you'll reach further and further.
You'll go far, lil anon, but only if you work for it.
