Don’t spend your time and energy thinking about what other people may or may not be thinking about you to the point that you forget to Focus on you. If they think negative about you, it’s their own business. If they talk about you, it’s their own cup. Let them bear it.
Instead, think about You and how you can become a better You. Spend time to devise ways in which you could align your life with God’s precepts. And always remember that There can only be one You.
