Photography is a great avocation. I am happiest when I have my camera around my neck. Learn to see the light in ways others can't and it will make a lot of difference in how that image is going to turn out in the end.
It is all about exploring and experimenting. Look for interesting subject, unusual light and shoot from a different angle even if that means going down on my knees for a different perspective. I am reminded of what I learned in one of my photography class - that when one first arrives at a location, to not snap way but rather spend time surveying the place for unique angle, interesting light - sizing and soaking up the image in your head....before you click that shutter.
Wrote an article a little while back on how to get started in photography if one has a limited budget. The article is here and at Helium if you wish to read more.
Enjoy and happy shooting.
