I have a daily motto I share with everyone I meet, every day. The motto is,
"LIFE IS not EASY, but IT IS SIMPLE.
Just BE NICE & SMILE!
That's all folks!
I hang a sign on my car and take it everywhere I go in London. It makes people smile in traffic, makes people honk their horns at me (in a pleasant and friendly way rather than road rage). Damn, people even take pictures of my sign and instagram it. Yet, invariably it makes most, sadly not all people smile. That makes them feel happier and me too.
