Pursuit of Happyness

Don’t ever let anybody tell you , you can’t do something .

There is no one else but you stopping you to do something .

If you’ve got a dream , you have got to protect and see it till you live it .

When people can’t do something themselves , they wanna tell you that you can’t do it either .

But if you REALLY WANT something , GO GET IT !
