Respect others because you respect yourself.
Respect is something that is earned. Before someone has earned your respect or after they have lost it all, treat them with decency because of the respect you have for yourself. When you are rude, cruel, mean, disengaged, or hold a grudge, you are only hurting yourself—you hold yourself back from your own progress. Whatever you do, do it respectfully, because how you treat others starts with how you treat yourself.
