How did you celebrate your last birthday?
I don't celebrate birthdays.
What's the last thing you bought yourself, just for fun?
Recently I bought a Walking Kit more out of desperation than for fun. It comes with a pedometer, a manual and a pair of wrist weights for the power swing. I still have not open the kit to read the manual nor try out the wrist weight. I have not done any walking yet as well. Sad...
What would the child you once were think of the adult you have become?
How did I/you grow old so fast? Why do you worry so much about what other people think about you? You should live life in the present and not worry about the past or be anxious about the future.
