Often, life is understood as a dream. But, in reality, many people fail to realize it's value. What people should understand is that life is more valuable than even a 100 carat of diamond. Everyone can get only one chance at life no matter how full of sufferings it may be. Even if such things as rebirth exist, we truly live only once. Life is to be lived as a gift granted to us by the nature of existence. This is our life. We cannot deny it or regret over it. The only thing we can do is to leave a mark of our existence in this huge world by doing something great and inspirational. Billions of changes occur in every second of life. But among all these changes, what matters is to realize the indefinable value of your life and existence. That is what makes life worth living.
