"don't share your problems.
80% of the people that you share your problems with don't really care anyway,
and the other 20% are kind-of glad that you've got them."
of course, real friends/family do care, but they also have their own lives to live, so problem-sharing is best kept to a minimum. .on the other hand, "describing challenges to someone who is equipped and ready to help with a solution" makes perfect sense.
