Here's an unfinished sentence I wrote and some of its responses from February 1992:
One obstacle that seems insurmountable but later turns out to be surprisingly easy to overcome is...
...public speaking. (Christina K.)
...driving an automobile. (Eric E.)
...growing up. (Cindy D.)
...fear of flying. (Leanne A.)
...meeting new people. (Angie F.)
...our own sense of limitation of ourselves and our love for others. (Colin S.)
...learning to live on four hours of sleep. It's not that bad, once you learn the secret to getting by on four hours is to sleep more. (Miranda G.)
...sudden and shocking disappointment. You just kind of expect it after a while, which is depressing, but oh well... (Jenni S.)
