Good begets good. The Golden Rule is universal. I believe that the universe will even things out for you in the end. If you want to be treated well, you need to treat people the way you want to be treated. There will be people who will challenge your mission of goodness, but you just need to believe that the universe is watching, and it will eventually even things out for you.
“The roots of all goodness
lie in the soil of appreciation for goodness.”
~The 14th Dalai Lama
