#1 Always carry your camera with you. Whenever you leave it at home, you will find a lot of things to shoot. Not all of them can be reproduced later on.
#2 Know how your camera works before going out to shoot. Otherwise you will miss many great shots, while you’re trying to figure out how things work.
#3 Fancy equipment doesn’t make you a better photographer. For example, better camera might have better image quality, but it doesn’t make crappy picture look any better.
#4 Make yourself comfortable before heading out to shoot. First of all, pack light. Photography is not fun, when you feel uncomfortable of carrying too much stuff. Secondly, satisfly your basic needs, like hunger and call of nature. It makes you feel more creative, when you don’t have other things in your mind.
#5 Learn the rules before breaking them. Start by learning and using rule of thirds. It will help to make photos aesthetically better.
#6 Take a lot of pictures. That way you have better chance to get the perfect shot.
#7 Think about the lighting. Sunlight is more appealing in the morning and in the evening, because the lighting is softer and less contrasty. Also it’s easier for your subjects not to be blinking their eyes all the time.
#8 Try to blend in. People are acting more natural, if you can do that. It will also improve your photographs. For example, don’t make your subject feel uncomfortable by using flash straight in their face unexpectedly.
#9 Find unusual angles. It makes even boring subjects more interesting.
#10 Try to improve yourself. First step is to be critical of your own work. Look at other people’s work too. Think about what makes a photograph good or bad. Learn from your own and other people’s mistakes.
