When asked what was the most important thing to me in life, I took time to think it over. If posed a couple of years ago, I would have answered 'Love' or 'Happiness'. That was what the teenager who had barely had any worldly experience would have believed in. But now, after meeting different kinds of people, after coming across different mindsets, I probably can conclude that you are the most important thing in your life. There is no one who will love you for what you are. No one will put your happiness before their needs. Nobody is born for you, except yourself. Whatever love you seek from the world, seek within yourself. What happiness you expect others to give, find it for yourself. There's nothing wrong in being self-centered. If thinking for yourself is called selfish, then please be selfish. If there's anyone worth fighting for, living for; it's you! Because everybody else is busy dealing with their own hassles.

Stop living for others, live for yourself. Love because life is a beautiful gift. When life shoves you into a difficult situation, face it and get yourself out of it. Everyone faces loss, heartbreak and sorrow, learn to talk as less about them as possible.
The world isn't there to help you up every time you fall, learn to stand up on your own. It is, after all, your life; live it the best you can.
