What don't you log?

I never log spices (with the exception of things like McCormick's packets). I almost never log mustard or relish, because I use a tablespoon or less of each and they're effectively 0 calories at that amount. If I'm using a single leaf of lettuce or a couple of grams of spinach for a sandwich or garnish, I don't log it. Really anything used as a garnish -- 10g or less of onion sprinkled on a taco, a 5g thin slice of tomato on an egg sandwich, things like that. I'm just too lazy to bust out the scale for a single paper-thin slice of veg or miniscule pinch of herb. Also, if I'm measuring out my coffee creamer and happen to pour 17ml instead of exactly 15ml I don't bother going in and trying to figure out what percentage of a serving an extra 2ml is.

Excepting the past couple of weeks, I'm usually under my calorie goal by anywhere from 200 to 400 calories, so I really do not sweat the small stuff, especially since it's not like I do all of these skips every day. It's been working out fine so far.

ETA: I also don't log the occasional single bite of something -- this was a bigger deal when I managed a kitchen (and therefore tasted things four or five times a day) but I still do it every now and then.

ETA 2: SON OF ETA: I don't know how I forgot this, but I don't log lemon juice! I've no idea why, because I probably use 2-5 tablespoons a day in my water, tea, salads, etc. I think it's a holdover anorectic behavior; in my mind, lemon juice is just "free" even though I know logically that it has calories.

Cheat days, spices and if the label says 0 calories.

Mainly just single cans of Diet Coke, and not even purposely; I just tend to forget because they essentially don't matter. I do log spices and mustard, but I also eyeball them a bit. I don't drink coffee, rarely drink tea and pretty much never have gum or mints.

I don't log my iced tea, diet coke, or splenda. I log everything else including gum.

If the label says no calories, then I don't log it. I don't log gum, spices, coffee (I don't use anything in it), or things like the handful of green onions I threw on my salad last night (it was an afterthought after I'd added everything else into my diary). I do not log any kind of activity unless it's dedicated exercise. Cleaning, cooking - those don't count.

I don't log:
coffee or tea, but I do log what goes in them.
sugar-free items or 1-2 calorie items like mints.
mustard as it's 0 calories, or any other spices & herbs unless it comes in a packet, like chili seasoning. I don't use enough otherwise.
celery that I have for a snack to avoid eating something I ought not to! There's so few calories that a stick or two isn't going to hurt.
anything as exercise except what I do at the gym or walks as my fitbit adjusts for that.
vitamins - that's just crazy... LOL!

There might be times when I have a little bit of something at the end of the day that I don't log but only when I know I am under. Also I am sure that I under-log my exercises because no two databases give me the same answer! So I use the lowest calorie burn and count any additional deficit as a bonus to my weight loss. That's also why I don't count any other exercise besides the gym and walking.
