them by.  I want  to shout  to  them all:" Wake up! You're still 1 0  ! What have you done today?" If you
want a happy  life, you can't dwell on (细想、纠缠于) your past   11   . If you want joy and love  in your  
life, you have  to choose  them  today. God gives us a new chance at  life every  time we wake up in the
morning. It is up to us to seize it.
