As I look around the point who are generally unhappy or disappointed in life, I see one commonality... they all hope that in their future things will change; but what people don't realize is that years go fast and days go slow.
As the days pass you only remember and cherish the good moments, always remember to live today as if it's your last day on earth, because it very well might. Don't get caught up in the past or the future, because the moment that should be most important to you is right now. Now I'm not saying fuck yourself up for the future, but don't forget about today, because that should be the most important day of all.
Now put on a smile on your face (: and take on the day as if it's your last!
