Be nice to those you meet - even if you don't want to.
Smile at those you meet - you don't know what they may be going through - you may completely transform their day (ever heard of the Butterfly Effect?)
Compliment the next person you see and watch their reaction.
Give someone a hand-up instead of a hand-out - there is a difference.
If a thought pops into your head from "out of the blue", it's usually NOT "out of the blue". Follow it and see where it leads. 💞
