The only problems you have left are the perfect ones. The imperfect ones, the ones with a clearly evident solution, well, if they were important, you've solved them already.
It's the perfect problems that keep us stuck.
Perfect because they have constraints, unbendable constraints, constraints that keep us trapped. I hate my job, I need this job, there's no way to quit, to get a promotion or to get a new boss, no way to move, my family is in town, etc.
We're human, that's what we do–we erect boundaries, constraints we can't ease, and we get trapped.
Or perhaps it's your product or service or brand. Our factory is only organized to make X, but the market doesn't want X as much, or there is regulation, or a new competitor is now offering X at half the price and the board won't do anything, etc.
There's no way to solve the perfect problem because every solution involves breaking an unbreakable constraint.
And there's your solution.
The way to solve the perfect problem is to make it imperfect. Don't just bend one of the constraints, eliminate it. Shut down the factory. Walk away from the job. Change your product completely. Ignore the board.
If the only alternative is slow and painful failure, the way to get unstuck is to blow up a constraint, deal with the pain and then run forward. Fast.
