Diversity...embrace it, rather than just accepting it.
It's not easy to see beyond your own frame of mind and thoughts of what a "norm" is, but when you stop for a second and reflect... what is a norm more than a subjective valuation of a world around us, looked at through our own glasses?
Instead, make a sincere attempt to see the world through the lenses of the person standing in front of you. He or she may be struggling to fit in.
Diversity is beautiful and adds value and perspective when we choose to look at diversity as a resource.
Work on your own perceptions all the time. I do and the older you get the harder you have to work on it. With age you show less tolerance for things that are different from the "norm" you have established. So never grow old in your mind!
Stay young at heart and embrace the diversity around you.
You will find beauty in it and the world will be a better place for it.
