Very often, I find happiness when I'm not looking for it.
Happiness is like the water or the wind; You can't keep it in your hands.
And also,you can't buy happiness: it's a feeling inside and sometimes there's not a special reason for it. Or, sometimes, very simple things: The sun, the sea, a friend, a special meal, a song, a dog......
But you can work for the happinnes: keep out your wrong feelings about yourself and the other persons and try to accept the problems you will find.
It's impossible to be always happy.
