"There is no greater joy, nor greater reward than to make a fundamental difference in someone's life" - Mary Rose McGeady
Making a difference does not have to be big. It can be done in a smile, a hug, a kind word, or a listening ear.
The truth is, you never know what someone else is going through. People do not always show that they're going through a difficult time. Even if it can be challenging for you personally, approach each person you encounter with acceptance, respect, love, and kindness. You will never lose out from being kind to someone and not expecting anything in return.
What you do and say can have a big impact. Your single act of positivity might just be the brightest moment in someone's time of darkness.
You make a difference.
