What secret thought have you been pondering lately that you've not shared with anyone?

Now, please don’t be a smart booty and say “If I share, then it won’t be a secret. <wink-n-smile>

This thought could be about anything under the sun, about you or about someone else.

What has kept you from sharing it (assuming it’s something share-worthy but not ready to be shared)? How could this thought affect you and/or others if you shared it with your S/O, closest friends, etc.? What would it take for you to act on the thought, if it’s about something you’d like to do?
