I would take that deal, then put it behind you and start on the next thing. Maybe it will be worth something some day.

However, move ahead and start work on your next thing. Don't delay--it is very easy to sit and stew.

Here is what works for me in serious times of stress.

Spend most of your energy working on your next deal.

And then, say, one hour per week, allow yourself to internally mope about this. I am quite serious. I call it "the hour of sniveling", and when that is done, you haven't necessarily solved a problem, but you have let those feelings express themselves, but then move forward.

(I admit this sounds very goofy, but I use this approach to positive effect.)

This isn't so goofy - it is like the same advice they give to people losing weight, they are allowed to have a pig out day once in a while.
