There are lots of people in this world who look at everything negatively, and only see the worst in every situation and every person. But whatever you do, don’t let these folk make you mean or hard-hearted.
Stay focused on what you believe, stay positive, and above all, stay focused on God and you will not been drawn into the negativity that surrounds some other people. If you trust fully in God, He will keep you true to Him and to yourself, by helping you to be positive no matter what life may throw your way, and helping you to try to do good even when those around you may try their best to bring you down by acting and talking negatively.
So don’t be hard-hearted, keep God at the centre of all you do because He alone can help you do His will.
