Why happy?

 Cheese!
 We say it to smile when we take any photo.Because we want to be good in photo.But we should always smile.
 Smile...I always make it.My teachers and friends say "You always smile.".It's true.I always smile.But I'm not optimistic people.
 I smile usually but I don't fell happy often when I smile.But I want to be happy.
 But I can't do it.I get sad easily then I cry.
 But I like smile.I like be happy.
 And you have to be optimistic.
 Look at yourself!
 Everthing gets better.
 Don't worry.
 Be happy
