You should have also mentioned the type of camera that you have and maybe somebody else can finish answering your question.
But here is some information to help you.
1. You should learn the technical aspects of photography and your camera (composition, shutter speed, rules of thirds, depth of field etc), once you understand these you will be able to create better images.
2. Shoot in "M" (manual mode) because you will have more control over your camera and not the other way around. When you are in one of the "Auto" modes the camera will just read the highlights and shadow areas and try to get you a picture. The camera is not smart enough to know what you are shooting.
3. You can start reading all kinds of books on this subject and get information from the internet. This includes web based classes, manufactures web sites to personal blogs.
4. Start shooting with your camera to get practice and from what you are learning from reading and doing you will get better. Practice does make perfect. Take notes while shooting and then look at your photos on the computer find the best one from that set and see what you did to get the shot and why you like it more than the others.
Since you have access to the internet here is a start: Some you have to pay for and some are free.. start with the free stuff of course.
