Look at the sky and believe that i can fly:)

I will do as usual but in a good mood ^^

Truly speaking, my expenditure on streat food increases.

Watch favorite (usually funny) movies and comedians. Find someone that needs help and give it to them. It doesn't have to be life-saving or even very important as far as the rest of the world goes, but it has an amazing power to bring one out of a bad mood.
