Think about it. Light is what photography is about. So, it's really important to notice it. The color, the direction, the shadows that result.
Next time you're driving an hour or so after sunrise or before sunset, notice the warm color and the long shadows. If you're driving North to South (or South to North), notice that one side of the road is in shadow and the other is bathed in beautiful warm light. Then ask yourself, in which direction would you want to look for photo opportunities?
The answer seems obvious in writing, but the majority of us have hundreds of sunset photos in our portfolios. Next time, try turning your back to the sunset and look for the photo ops that everyone else misses. The joy you get from being the one person in a crowd who's facing the "wrong" direction is a great bonus too! ;-)
