These words are the wisdom of Charles Swindoll:
Attitude is more
important than past, than education, than money, than circumstances,
than what other people think or say or do. It is more important than
appearance, giftedness or skill. It will make or break a company, a
church, a home.
The remarkable thing is, we have a choice every
day regarding the attitude we will embrace for that day. We cannot
change our past. We cannot change the fact that people will act in a
certain way. We cannot change the inevitable. The only thing we can do
is play on the one string we have, and that is our attitude.
