Sometimes people come into your life and you know at once that they were sure to be there．They serve some certain purpose，teach you a lesson or help find out who you are or who you want to become．You never know who these people may be：your classmate，neighbor，teacher，long-lost friend or even a real stranger．But you know that every moment they will influence your life in some serious way．
Sometimes things happen to you．At the time they may seem terrible，painful and unfair．But later you realize that without overcoming those difficulties，you would have never realized your further ability and advantages．Everything happens for a reason and nothing happens by chance or with good or bad luck．
The people you meet influence your life，and the success and failure you experience create who you are．Even the bad experience can be learned from．In fact，they are probably the most poignant and important ones．
Enjoy every day even every moment and take from it everything that you possibly can，for you may never be able to experience it again．Talk to people whom you have never talked to before，and really listen．You should set your goals high，hold your head up，tell yourself you are a great one and believe in yourself．
You can make your life anything you wish．Create your own life and then go out and live it．
