Why would I?
Wear a mask.
Commit to that project.
Take the first step to mend a relationship.
Respect the rules.
Be kind to others.
Pay taxes.
Give back to the community.
Sit down and just listen.
Not lie.
When nobody else is doing it?
It is a way of hiding that lowers the bar. In your family, your company, your circle, your life. Chances are that nobody is acting out of habit, ignorance, laziness. Perhaps all they need is somebody who shows them a different way.
That somebody could be you.
