When I was a child, after bedtime I would often  (3)  my bed in my sleeping clothes, go to the  (4)  and stare at the stars. I had so many questions. How far away were those tiny points of light? Didspace go on_  (5)  and ever, or was there some end to space, some giant edge? And if so, what  (6)  beyond the edge?

  (7)  of my childhood questions: Did  (8)  go on forever? I looked at pictures of my parents and grandparents and tried to  (9)  their parents, and so on, back through the generations, back and back through time. Looking out of my bedroom window  (10)  _the endlessness of space, time seemed to spread forward and backward  (11)  , swallowing me, swallowing my parents and great-grandparents, the whole  (12)  of earth. Does time go on forever? Or is there some  (13)  of time? And if so, what came before?

When I  (14)  , I became a professional astrophysicist.  (15)  I never answered any of these questions, they continued to  (16)  me, to affect me, to drive me in my scientific research, to cause me to live on just fish and no sleep for  (17)  at a time while I was  (18)  a science problem.

Sometimes people come into your life and they were meant to be there to serve some sort of propose, to teach you a lesson, or help you   (1)   out who you are or who you want to become. You never know who these people   (2)   be, but when you lock eyes with them, you know   (3)    that they will affect your life in some profound way.

   And sometimes things happen to you that may seem horrible,    (4)  , and unfair at first, but   (5)  you find that without overcoming those obstacles you would have never realized your potential, strength, will, or heart. Everything happens   (6)   . Nothing happens by chance or by means of good or bad luck.Ⅲness, injury, lost moments of true greatness, and pure stupidity all occur to test the    (7)   of your soul. Without these small tests,    (8)   they may be, life would be like a smooth, straight road to    (9)   . It would be safe and comfortable, but dull and entirely   (10)    .

   The people you meet who   (11)   your life, and the success and downfalls you experience, help to create who you are and who you become.   (12)   the bad experiences can be learnt from. In fact they are probably the most important    (13)   . If someone hurts you or breaks your heart,   (14)   them, for they have helped you learn about trust and the importance of being careful    (15)   you open your heart. If someone loves you, love them back,    (16)   because they love you, but because    (17)   , they are teaching you to love and how to open your heart and eyes to things. Make every day   (18)   . Appreciate every moment and   (19)   from those moments everything that you possibly can, for you may never be able to experience it again. Tell yourself you are   (20)   and believe in yourself, for if you don't believe in yourself, it will be hard for others to believe in you.

“In university open days with my daughter, I promised not to ask any questions — in case I asked embarrassing ones,” says Mike Nicholson, director of admissions at the University of Bath.
