Clear your head. Block every thought that tries to make you- well, think.
Try to remember what it was like to be somewhere else; another time, another place.
Do you remember what it was like to be fifteen?
Do you remember what it was like to be ten?
How about five?
Do you remember what it is like to be in the country side; the air, the quiet, the nice people?
How about a loud city?
Notice the beauty of nature.
Feel the summer breeze.
Listen to the birds sing.
Stare at the clear blue sky.
Pick up the phone and call an old friend. Remember the good times.
Help the needy.
Spend time with people you love.
Write a letter to your future self.
Just do something.
