Running is an amazing experience. Not only do you feel more confident about yourself and your body, but the endorphins after running make you feel happy, full of energy, and excited to be alive :) If you time yourself every once in a while, it is an amazing experience of self-determination, trial, error, and sucess. By overcoming the limitations of your body, you develop a sense that you can do anything, that you are unstoppable. and indeed, you are! :)
