Pretty simple. You've done this before, you've done it for hours across your life. You've done it 499 times. You know you'll pick Prussia again. Why do you do this to yourself?

I told you. You told you. You knew you would. You dread the reality of what will happen next. You know you'll set up your taxes and budget. You know you'll set up your clergymen or intellectuals (you're playing modded, probably HPM or HFM). You even know which provinces you'll put them in. Its muscle memory by now. Dread washes over you.

Why. Why. Why. Why. Why. Why.

Yes, you'll spread them out in the same spots you've decided 450 games ago. Yes, you'll fix the non-Hussars to be Hussars, and you'll make sure everyone has that perfect ratio of artillery. You know you won't even last until the units pop up.

So you've done your budgeting, your diplomatic stuff, your spheres, you micromanaged your armies (this time, good job for lasting this far!), but now it's time to start not playing.
Press the space bar.
Now, you feel the depression wash over you. It's January 3rd, 1836 and some random crappy country refuses to pay you it's loans. You sigh. You want to cry. You alt-f4 the game.
You now are ready to go back to looking back at your Steam Library, and eventually settle with YouTube.

You'll do it again in a few weeks.
