Life's marathon brings you across many different people. There are people of all types you can choose to admire and learn from. Sometimes, though, you come across people who believe they are entitled to all of life's many blessings without having worked hard for it. They encounter confidence and persistence and don't know how to understand or appreciate it.
Do not let these people suck you in or drag you down. Continue going. Finish strong, learn from your experiences and give the gift of yourself to others who are open to becoming better more productive people.
Keep going. Life is an emotional marathon...and it's just too short to live it in any sort of conflict.
