Let's say one of your important goals is to lose weight. Get some poster board, and make your own posters that say, "I weigh X pounds," where X is your goal weight, and put them up around your house. Change your screensaver to a text message that says the same thing (or to some equally motivational imagery). Get some magazines, cut out pictures of people who have bodies similar to what you'd like to have, and put them up around your house. Cut out pictures of healthy food that looks good to you, and post those around your kitchen. If you work in an office, then alter your office in the same manner. Don't worry about what your coworkers will think, and just do it! They may poke a little fun at you at first, but they'll also begin to see how committed you are.
