The core of it
Expression, creativity, visibility. Also a nudge that someone around you is waiting for you to speak.
In love
Say it. Guessing will not resolve this one; speaking gives you options.
In work and money
Good for publishing, presenting, submitting. A plan kept in a drawer never argues for itself.
One thing to do today
Send the line you keep deleting.
A number is not a verdict. It says what you are noticing, not what you will get.
