Be respectful to your superiors, if you have any.
If you want to be a great leader, remember to treat all people with respect at all times. For one, because you never know when you'll need their help. And two, because it's a sign you respect people, which all great leaders do.
In the household in which I was raised, the themes were pretty simple. 'Work hard. Don't quit. Be appreciative, be thankful, be grateful, be respectful. Also, never whine, never complain. And always, for crying out loud, keep a sense of humor.'
Be respectful of words. They mean something.
Respect is the most important thing. Be respectful toward others and have respect for yourself.
We have to be respectful to one another.
Work your ass off. Don't be an asshole.
Don't waste time on what's not important. Don't get sucked into the drama. Get on with it: don't dwell on the past. Be a big person; be generous of spirit; be the person you'd admire.
