So what does this have to do with the job search?
The Dip is flexible. It responds to the effort you put into it. In fact, it's quite likely (in almost every case) that aggressive action on your part can make the the Dip a lt worse. Or a lot better. Let's try for better.
When the pain gets so bad that you're ready to quit, you've set yourself up as someone with nothing to lose. And someone with nothing to lose has quite a bit of power. You can go for broke. Challenge authority. Attempt unattempted alternatives. Lean into a problem; lean so far that you just might lean right through it.
If you have not done the preparation to be sure the track you are on is the proper one, be careful how far you lean.
If you have done the preparation and are convinced that you are on the right path, it is good to lean. Don't quit! This could be the break through you were looking for.
Is there anything you would add to this?
