Instead of comparing where you are with where you may have been, spend the energy enjoying it. Savor the people that you are with and appreciate their qualities, instead of wasting time comparing them to others.
Enjoy where you are and get involved, and God will see to it that you go somewhere else if it is His will!
Learn that where you are is an appointment. You are there to either give or receive. You are not necessarily there to critique and compare.
God knows your heart. He knows where you are. He has not forgotten you, and He slumbers not!
