When ever feel sad follow my list and if you are happy then also you can...
Listen Songs
Have walk
Have a sleep outside with nature
Watch a movie new one
Have a taste food
Read a cool crazy book
Chat with friends
Go to ground for playing
Spent time in shopping
Have something called adventure
Do some experiments if you like Science
Do do anything as annoying
Have computer games play
Here it doesn't not end's here. there is more & more to see , listen,do untill one stop his life
