Here is a quote by Ralph Marston that I thought I would share with you:

"The people whom you find most difficult to deal with can also
be your most valuable teachers. For your problems with them are
not really due to how they are, but rather to how you respond
to how they are.

Learn to deal successfully with difficult people, and you learn
valuable lessons about yourself. Work to relate positively to
difficult people and you develop skills that can serve you well
in many other challenging situations.

People are the way they are. Get past the need to try to change
them, past the need to judge or condemn, and look for the value
they offer. Sometimes that value is deeply hidden, and when you
find it you've found a real treasure, something few people take
the time to uncover. In every difficult person you encounter,
make a point to look past the difficult part and focus your
attention on the person part.

The other people with whom you interact are mirrors that help
you to see things within yourself. With some people, that mirror
can be difficult to view, yet when you have the courage to do
so, the rewards can be many and great."
