How to SMILE more often and spread the smile more to others?

I started a day with a smile (though it is meaningless)... going to my company with saying "good morning" to everybody with smile... that are habits that many of Vietnamese donot have...

Then, my colleagues reply me with smiles as well

There is many ways to smile but i love this principle of the Laughter Yoga course that I joined: FAKE IT FAKE IT UNTIL YOU MAKE IT. Basically when you smile (fake or real), the body release good hormone that make you feel more relax, take thing easier and less stress. This doesn't mean you send fake smiles to others it mean, in any situation, even tough one, KEEP SMILING:). Cheer and smile more...

Hãy tạo ra niềm vui cho mọi người, khi đó chúng ta sẽ có nhiều nụ cười hơn,

Understand and trust the good in everything. Smiles come from within. Don't let it depend on what "happens" to you, but how you decide to respond to that. Don't just smile with your lips or face. Be a smile and forget the rest. People around you will, most of all, feel it, rather than see it... and so it becomes contagious. They get infected by you and, without noticing it, their lives change and they go home later infecting their own.

I read these 3 letters somewhere and want to re-share:

Sincerely,
