Surprise your Muscles

Its ok to have a workout routine, but it's not ok to keep your exercises the same all the time if you want your muscles to grow. Whenever you try doing push-ups, per se, you should change the way you position your hands once in a while. This will exercise different areas of your pectorals, strengthening the overall muscle, and will also have a positive effect on your shoulders and your triceps. Also, this practice helps to stimulate muscle growth. Its all about experimentation. Try out different exercises, and as you learn more, switch them around in your routine. Don't be afraid to try different workouts, well, as long as it's safe and they don't hurt your muscles.
