Next time on a trip save a little room on your camera for a little series photography.
When my wife and I were in Ireland we made a few collections of photographs all centered on a common subject. I did street lettering, she did gates.

Exercise #2: Grab your camera. Over the next week or so, focus on one idea – leaves, grass, twigs, soda cans, poo – whatever you like. Take pictures from different angles and in different light – see what series you can come up with.
Bonus: Combine them into one image or have them framed together.
