1. Just do You!
We often overlook the simple concept of taking our own skills and using them to help people for no other reason than we simply can. So whatever your skill is; music, art, math, building, programming, listening, talking, teaching, and so on. Just do it to help someone because you can.
Believe it or not smiling is infectious. When you are walking down the street just wear a smile. Every person that looks at you will likely smile right back. It’s the little things that brighten a person’s day. You may not be able to fix all that is wrong with the world in a day but a smile passed around the world is a pretty good start.
