Life.. A journey, that is full of uncertain things. The only certain and constant thing in life is "Change". The only thing that'll stay with you, no matter what. It stays with you in your bad and in your good. When your life is full of joys and all the happiness of the world.. It changes. When you're going through the worst time of your being, it takes time.. but it changes, eventually.
Change is what we all look forward to. If its bad, we want to change it for the good, if its already good, we want to change it for the best. The more things change, the more they stay the same. And sometimes, change is good, sometimes, change is.. Everything. All in all, we all want change; we all 'need' change.
