You may very well be past publication time by now, and I did notice that there hasn't been a comment to this thread since December, but I figured what the hey.
All of the following are from Small Favor, so I used the spoilery thing just in case, even though I don't think most of them give anything major away.
For Investigation:
p.323
"You got through with a tracking spell?"
She shook her head. "No, it failed miserably. So I was forced to resort to the use of my brain."
or: p.67
"Then what?"
"I ask people impertinent questions," I said. "Hopefully turning up pertinent answers."
For Survival: (Something other than animals--I'm assuming you use this skill for matters of wilderness survival as well. :)
p.346
Michael had planned ahead. He had a dozen chemical heat bags with him, the kind made for hunters to slip into the wristbands of their coats. He passed them around to us and we put them inside our socks after we waded ashore. Otherwise I don't know if we would have made it through the snow up that hill, not with our pants soaked to the knees.
or:
p.300
This one is Actually pretty spoilery! Nicodemus waited for me, stylishly casual in a deep green silk shirt and black trousers. I shivered when a breath of cold wind touched me, and my weary muscles threatened to go out of control. Dammit, I was the one working for the Winter Queen. So how come everyone else got to be perfectly comfortable in the middle of a blizzard?
For Whatever skill you use for cooking: Possibly Craftsmanship?
p.288
It turns out that Molly wasn't her mother's daughter in that respect. Charity was like the MacGyver of the kitchen. She could whip up a five course meal for twelve from an egg, two spaghetti noodles, some household chemicals, and a stick of chewing gum. Molly. . .
Molly once burned my egg. My boiled egg. I don't know how.
For Whatever skill you'd use for reassuring someone:
p.296
Harry's letter to Ivy (the whole thing isn't that long.)
Hope there's still time...
I'm surprised nobody's posted these.
The first is pure unadulterated
Craftsmanship:
"She [Charity] put the hammer over her shoulder, balancing its weight with one arm, and turned to me. She looked ferocious, so armed and armored, and the heavy black stain around her eyes didn't do anything to soften the image. Ferocious, hell. She looked competent-and dangerous.
Everyone just stared at her.
She arched a golden eyebrow,'I make all of my husband's armor,' she said calmly, 'as well as his spare weaponry. By hand.' -PG, 326
Discipline:
"I opened my eyes and everything came into a brilliantly sharp focus that discounted the existence of anything except myself, my magic and the ritual awaiting me. It had been a long, wearying preparation, and I hadn't even started with the magic yet, but if the spell could help me nail the bad guys quicker, the hours of effort would be well worth it.
Silence and focus ruled.
I was ready.
And then the F**king phone rang about a foot from my ear." -PG, 53 (paperback)
Another:
"Stupid phone. Stupid car crash. I tried to think positive, because I read somewhere that it's important to do that at times of stress and frustration. Whoever wrote that was probably selling something.
I picked up the phone and growled, 'Screw thinking positive,' into the headset.
'Um,' said a woman's voice. 'What did you say?'
'Screw thinking positive!...'" PG, 54
This one's from Small Favor, So I put it in spoiler tags.
"Hey, you try coming up with a cogent, rational course of action when you're running down a frozen alley with genuine fairy-tale creatures chasing you, spitting bullets at your back. It's way harder than it looks."
-Small Favor, pg.52
Empathy:
"'Morgan,' I said, 'Stars and stones man. Please don't do this. She's a child. We should be helping her.'
My words slowed him, and he froze in place for a terrible heartbeat. Then he closed his eyes and swallowed, his face twisting with nausea. He opened his eyes again and whispered, 'Step aside, Dresden. Please.'" - PG, 444-445 (Paperback)
Resources:
"'Wizarding doesn't pay much,' I said, 'You'd be surprised how much stuff I get from Wal-Mart.'" -PG, 182
Another non-Spoiler from Small Favor and it might also work for Discipline:
"The prime rule of combat wizardry is simple too: Be prepared."
-Small Favor, pg. 102
