The three truths every person needs to come to are the truths of their value, their purpose, and their destiny.
In life, people constantly put themselves down. If someone with no arms or legs can be considered "cool enough" to be your friend despite the teasing and bullying, it proves that external appearances don't truly matter.
Why then do we tease each other based on how we look? Recognize your inherent value and stop letting discouragement take you away from your true potential.
