If you grow up with parents who genuinely champion you, you will most likely succeed. If you have parents who demean and belittle you, you will either settle for mediocrity or have a much harder time overcoming those negative sentiments.
Do you know that the God of the universe is crazy about you? He looks at you and sees something good that He created. He sees His Beloved. He sees Jesus.
Maybe if we looked for the best in others and pointed it out to them when we saw it instead of competing with and criticizing them, both we and they would turn out to be better people than we currently are.
Just food for thought.
