Life Begins

Where does life begin? Everyone has a different answer. I'm so confused. Does life begin at true love? Or when you finish your education? Some say life begins at birth, but other say life doesn't begin until you have a significant other and children. Many people claim that life doesn't begin until your completely happy and in control of yourself. But what is the truth? Is there a beginning to life? Or is it all in our heads? I think only pieces of life begins at a time. Your life as an adult begins at 18. Your life as a teenager begins at the age of 13. 

Life begins in pieces. Once one thing begins, something else prepares to begin. But these pieces in life must come to an end. Whether it ends in 5 years or 50, it will eventually be over. So, we have to live our lives while we can. We need to put happiness before depression. We don't know when everything will just drop and disappear, so why not enjoy it while we can?
