No project is conceived in a vacuum, no decision in isolation and no negotiation with a clean sheet of paper.
But do you know what you're not willing to consider?
If a newspaper company is planning its future, is shutting down the printing presses an option even being considered? Or is it off the table?
Plan a rabbi's wedding and you probably shouldn't even bother to pitch BLT sandwiches or lobster. It's off the table. Not being considered.
Personal marketing plans run into the unstated table problem all the time. Is it off the table for you to quit your job, drop out of school, go back to school, speak up to your boss? I'm not asking if it's going to work or not, I'm just wondering if the possibility is even on the table. If you're not willing to consider it, you can bet you're going to sabotage the thinking that goes into evaluating the choice.
Big marketing breakthroughs always come from doing something that everyone else says is off the table.
