If you look around for fairness, you will find little of it.
Different people see the world in different ways, and fair becomes a fluid concept when you change perspective.
If you look inside for fairness, on the other hand, that is something you can more easily work with. You can train it, build it, apply it, and eventually spread it around. You can make it contagious, and impact those who are close to you.
And it all starts with being fair to yourself. What can you expect of you? What will you hold yourself accountable for? How will you express this to others, how will your actions impact them, and how are you going to find out?
Before asking the world to be fair, ask that of yourself. Imagine if everyone would do that.
