Do not judge other people by their outward appearance. It takes a lot of courage and strength to be happy inspite of whatever hardship a person is going through. Treat everyone with kindness and respect because regardless of how they truly feel you can make a positive difference in their lives.
Most times we only realize how blessed we are when compared to our minor problems we see the pain and distress others are going through. People don't publicize their problems on their forehead so we need to show love no matter the other person's countenance. It only takes a brave person to keep that air of happiness around them regardless of what they are going through. Do not base your judgement on assumptions.
Be thankful for what you have because you don't know what that other person is going through. You don't know what you have until you get into another person's very uncomfortable shoes.
To all sickle cell Warriors out there smiling amidst their pain and for all those fighting one battle or the other, stay strong, be brave, God's got your back.
