You are not a smiley but a real person with real feelings. Feel what you must, deal with it the way you must but never smile just for the heck of it. Your smile is worth so much more than being used for hiding your true feelings.
Smile when you have gotten up even after you’ve fallen. Be proud of yourself for not giving up. Believe in yourself even stronger than before because you had the courage to start over.
Your drive to reach your goals should come with a vengeance of positivity. No matter what, do not quit!
