Here are some lessons I learned in the last few hours:
1) IF you spent a lot of time pondering paint colors and finally made a decision on just two colors to use throughout your ENTIRE home with a certain brand, STICK TO THAT DECISION.
2) BECAUSE it will be very easy to get swayed into changing to "close enough" colors when you can only meet the person painting your house at dusk after a grueling day of work. Mostly because you discover he gets a discount on a different brand because it will save a) time and b) money.
3) ESPECIALLY because you will want to throw yourself out a window when you walk into your home and realize that instead of gray, every single wall is one of two shades of purple. Not because it's ugly, but because it wasn't what you wanted and it was ALL BECAUSE OF HASTINESS.
4) AND THEN you will have a toddler-style meltdown because you realize that yes, you guess you DO remember signing off on a swatch called "Mysterious Mauve," and you did mention that it looked kind of purple at the time, but didn't really think hard about what that means. You'll want to kick your own butt into next week.
5) SO you start scheming to try and mask the color with lighting and draperies and distracting furniture, but you know in your heart that every time you look at any wall (and they're EVERYWHERE) you'll be reminded of what a moron you are. And you decide you MUST find a way to ask the guy to re-do it, even if your budget is at negative eleventy hundred dollars already.
6) OH BUT THEN the painter quotes you even more than you dreamed it could cost, a ridiculous amount when you find out YOU HAVE TO BUY THE NEW PAINT, and you calculate that this re-do will cost exactly 75% of what the original quote was, even though that quote included many tasks that would not need to be re-done. But the dude now has the upper hand, so there's not a lot of room to negotiate, what with you buying $30+ gallons of paint.
7) THEN you will hem and haw and imagine you just inherited a ton of money to re-do this, knowing inside you must do it to protect your sanity.
8) AND THEN you will cry, thinking about all the stuff you would rather do with that money.
