If you don't keep a camera of some sort with you all the time you should. I can't tell you how many times I stumble across something and say "I wish I had my camera". For those of you who say "just use your phone", my phone camera sucks. I use a little pocket camera now. The thing is, you never know when you will see a great grab shot.

I was in Florida a few months back and had some time to go out and shoot on the beach for a couple of hours in between meetings etc. I had my trusty brick of a medium format camera with me. I had a great time shooting and was headed back to my hotel room happy with what I shot. On the way up to my room I walked past the bar and just happened to glance over as I walked past. Holly smokes! The afternoon light, streaming through the windows, played perfectly with the architecture of the space. I stopped, pulled out my camera, took one exposure and moved on. Below is the quick grab image I have now because I had my camera at the right time. This one didn't get away.

Keep your eyes open always looking for images, even if you don't have a camera with you. Stop and take a look at the world around you, it makes you think. Then, when you do have a camera, you will be able to capture what you are seeing.
