look forward! There is no looking back now.
Life is like driving, if you look back you crash. There will always be something in front to reflect the past so you don’t have to worry of forgetting. You have to drive your own car and not crash into others for it’ll do both of you harm… and finally the outside shell doesn’t always define the driver.
If you have a rotten attitude change it, it’s like driving with flat tires, you can’t go anywhere with it.
