Keep your Camera with you at all times.
Some of the best pictures happen when you least expect them. A candid of a child that captures them just the way they are. A picture of an animal in its environment. Sometimes you never know when the right moment will hit or when something will catch your eye. If you keep your photo equipment really simple, just your bag and camera, you will be ready to go. Your cell phone can work too. Just take a picture to remember a location that you want to return to at a later time.
