Attitude

I think that most of our reactions depend on our attitude,

Sometimes you feel so depressed and sad, then you hear a joke, you won't laugh.
but if you are in a mood of laughing, any silly joke you hear, you will laugh at.

If you like someone and he told you an idea, you will find yourself convinced,
but if you don't like him, you will reject hearing any idea from him.

If you are not feeling good and then go out to a new place, you won't feel satisfied even if you are with ur friends, yes you might feel better but your deep sadness won't disappear,
but if you are happy or heard good news, any place you go will find it a good change.

If you are so sad and many bad things happened to you, then a more slight bad thing happens, you will find yourself crying.
but if you are ok, you will feel any bad thing can pass safely.

and many many examples....

So it is all about your attitude, so try to keep it up.
