Yes and No. Opening and Shutting.

Last night at a meeting, I shared with friends that I am troubled by the number of things I want to do. I worry that trying to do too much can result in doing very little at all.

To which one of them replied, "If you are willing to say 'yes,' you must to be willing to say 'no.'"

Her advice seemed related to the aphorism: "For every door that opens, another closes."

Was my friend saying that many of the those closing doors are ones we must shut ourselves?
