I was driving down the highway and I saw a very colorful tow truck at a rest-area as I was driving past. I was thinking to myself, I should get a few pictures of that. The other side of my brain said "Just keep driving, it will take to much time to stop and take pictures." I made the decision to turn around and take some pictures and was rewarded as I was able to get the above shot of which I am very pleased of the final product.

That is really how photography is. If you don't take the opportunity to take pictures, or you are too shy to get into interesting situations, you may lose the chance to capture something amazing.
