It is our choices that show what we truly are, far more than our abilities. Choose to change for the better.
While God gave everyone a different level of ability, we all have the ability to make the right choices. Look for someone around you that makes good Christian choices, and follow their example. Surround yourself with the kind of people you want to become.
Do not associate with a man given to anger; or go with a hot-tempered man, or you will learn his ways and find a snare for yourself.
