You're not the only one trying to learn Digital Photography, my friend.
I don't know about you, but I can still tell you that there are sure fire ways to learn and even become a pro in Digital Photography.
Your first question, I assume, is "HOW?".
Well, here are some easy tips you can use to start taking better pictures with your digital camera:

• Equipment - Get some better equipment, seriously.
  Your pictures will drastically improve if you get some better equipment.
  I mean things like better cameras, tripods, lighting and things like that.
  Tripods are great because your photos will always be completely "straight", if you know what I mean.
  No shaking or anything so they're never blurred out at all.
  This is especially true if you work outside taking pictures at night, it can be a real pain to get good and non-blurry photos.
  
• You're gonna hate me for this but...
  Practice.
  Believe me, in the long run the one thing that it all boils down to is practice.
  Sure, there are lots of great courses that will help you learn faster, but you're not going to get better at all if you don't practice.
  

It does not matter if you're 'on the right track' or not, if you just sit on your bum on the track, instead of running to become a world champion.
You know what I'm saying here? Good equipment and practicing with that equipment will go a long way for you, so the moral of the story is really to take action and do SOMETHING!
