Good topic, we needed it!
I'll say what I posted before:
With some practice, you'll get good in no time. For starters, know who or what you are drawing. Analyze some pictures of your subject, get to know the features well. Also, don't just try to draw from memory, it always helps to have a reference picture to help you out, at least until you are super comfortable drawing that one thing. Always start with the outer lines, save details for later, or it could very well mess you up. Take your time, don't rush your art, and learn at your own pace. And most of all, don't give up! It may take several tries, but you'll get it with some practice. Hope this helps!
