We're all born unique with our different strengths and weaknesses. A blend of the good and bad.
No two people are the same and trying to imagine everyoneof us having three similar traits doesn't come off as possible. But in that we all could, and I can make a choice of what it would be, here are the valuable traits I'd push for:

EMPATHY
I say this a lot, that the very day everyone assumes upon himself an empathic lifestyle will be the beginning of healing and positive outputs in our world. I'm big on empathy. On being humane. We all can sdo with a little kindness and compassion.
Empathy is simply treating another as you would like to be treated. It is not trying to feel, but, feeling and understanding others truly. The world is wild, it's crazy. People are going through a whole lot. Actually, everyone has their own share of crisis. Showing some love wouldn't hurt. If we can't help another get through their crisis, we definitely should not make it any harder for them. Love is supreme.

FORGIVENESS
Some time back, I read a book titled "I forgive for my sake." I learned better from it how important it is to bear no grudge. In life, people would always offend you, consciously or not. Just as you will to others too. That cannot be taken away from human nature but then, your reaction to it lies in your hands.
Notice that when you reconcile with someone after a time of bearing grudge and keeping malice, you feel like some weight has been lifted off of you. Do you notice how lighter your chest feels and easier your breath flows? If you do, you'd agree with me that in those times of grudge, you've caged yourself. You've only been hurting yourself more. Some persons go as far as bearing so much bile for long against a person who is oblivious to it. I ask, to whose detriment?
Forgiveness is a gift you give yourself. Life is too short to go about with bitterness and a heavy heart. I learned to forgive people for my own peace and well-being. No one is perfect. No, not one. It's heartbreaking to see people hold so much angst and animosity, even towards people they claim to love and worse even, for flimsy reasons. None of that bile is necessary. Un-forgiveness is a thief of peace and unity. We could do without it for our own sakes, first. Forgiveness, I tell you, is cheap.

AUTHENTICITY
I once was coerced into speaking to a group of young persons like myself. I don't know why but all I could think of was Authenticity. Staying true to ourselves. Bring first class versions of us. In today's world, there's a crowd of people who are exactly alike, or pretending to be. We're so ashamed of our true selves, our identities, hustles, backgrounds, and everything that makes us us. It's very appalling.
Some persons have very much been rooted in living a life that isn't theirs, trying to fit themselves in a box of what they assume as the originality of life that they've forgotten what it's like to be themselves. They've painted a faux image of what they assume they should be, that they don't realize how much of a sham and second class versions of another person that they are. We need less of that.
It would be such delight if each person wears their true selves like a badge of honour, unapologetically embracing our strengths, quirks and vulnerabilities. We cannot all be same. In our diversity lies our uniqueness. And in that lies the spice out world needs.
