Happy formula

I had discovered a happy formula since months ago.
In fact, it has helped me a lot throughout the road.
Just an easy formula to make you happy.
Actually, what you can do is just think of the happy things happened around you today and what happy things that you going to do on the next day.
It was 0017 now.
Happy things that happened today around me was having a nice breakfast, nice dinner, and so on.
What happy things that I am going to do tomorrow?
Probably, level up in Restaurant City, play few nice FIFA matches, meet some nice friends, meet classmates that not seen for 2 days, and so on.
Life is just few decades.
Although wars still on and bad things happen around, life still on and cheer up.
Instead of facing life with sadness, why don't we face it with positive thinking?
I hope so.
