I procrastinate a lot. Like, a looooooooot. More than anyone ever should. Other than that, I put random objects in my mouth sometimes. Things like a pencil/pen, a piece of string, random plastic objects, and etc... I'm not why I do this, but it he- right as I was typing this, I unconsciously put my headphone cord in my mouth. Anyway, I feel like it helps me focus somehow, or stay sane, because I really can't sit still otherwise. This isn't really a habit, but more of a choice (a life-style, if you will), but I always go to sleep at 4, 5, or 6 AM nowadays, unless I absolutely need to wake up early or am exhausted from the day I had. It's been that way for about... probably over a year now. I realize that it's better to go to sleep early instead of staying up all night on the computer/phone, but... I don't really have a reason to stop doing it yet, so I guess I'll continue doing so. Similar to others, but not exactly the same, I pick at my nails (not bite). I find nail biting to be kinda disgusting, actually. But I pick at them so that they don't get too long, because long nails are something I don't enjoy having.
Biting my fingers. Terribly odd habit that I REALLY need to stop. I'll mostly do it when I'm concentrating super hard on something. Not good...
Procrastinating is surely a bad habit, but I had another less common (I guess...) I kept removing little bits a skin next to my nails despite knowing how bad it was. Also weird fact, I ate them. They taste good – I guess that's why I did this for so long. I like the taste of my own skin wtf XD I managed to stop doing it to my nails but unfortunately my lower lip is still suffering of it :/
when im super concentrated i bite my hair. i dont chew on it or anything, just bite it and keep it in my mouth. i can't tell you why. i also procrastinate really bad on everything, especially art hmm.
I pick at stuff. I pick at my nails, so I don't usually cut them - though my nails aren't constantly short, which is a problem for piano. Often I'll try to stop picking them and let them grow out, but then something happens and I start picking at it just to even it out aaaand then I have no nail. I also pick at dried skin on my lips (they bleed so often that I've started biting my bottom and sometimes my top lips out of pure habit) and dried skin basically anywhere else. This usually happens when I'm doing something idle like reading. Oh, and I sit funny. I like having my legs swung to either side of me, not in front. During lunch I like sitting on the outside of tables, and I prefer the isle seat for that reason. But I also cross my legs and jiggle my feet. Especially when sitting at the dinner table, this is annoying, because then I'm knocking my foot against a table leg and taking up someone else's leg room. But I like it >.>
I trim my nails with my teeth instead of with clippers because using clippers is SO awkward and irritating to try and use. I don't bite them idly anymore, though. My biggest bad habit, though, is always putting myself down (as I'm sure a number of you have noticed). It's something I lived with for a long time, so battling against it now is difficult at best, but I know who + - and Whose I am now so I have hope that I can beat it.
I could sing you a song about my bad habits I do not ever know what to do with my hands. Unless I have a crutch like a book, this manifests one of two ways. I have two options for sitting. One: perfectly, absolutely still, barely moving to breathe. Two: Still except for my hands, which, nine times out of ten, are picking at my cuticles. It's a habit I should really stop, but I just can't. If there's skin out of place, it bugs me until I 'even it out' (remove it). If I'm bored, feel out of place or awkward, or just because, I'll start doing it again. My nails look like Ant-Man's taken a very small band saw to them. If I'm standing, my right arm hangs at my side while my left hand touches my right elbow behind my back and usually starts rubbing at the skin there, which, coupled with my insistence in T-shirts, makes the skin really irritated. If I can't do that, my hands automatically go in my pockets. If there's no pockets my hands literally just end up floating where my pockets usually are, no joke. It looks exactly as stupid as it sounds. #MissingNo
I have a bad habit of leaving cups/drinks lying around the house >_> Only to find them a few hours later and realize the drinks are now warm and gross with a puddle of condensation around them.
I get distracted easy and not pay attention, when someone is conversing with me... I bite my nails... still. at my age. I use aliases no one can understand but me.
I bite my nails and the skin around them a lot. Have since I was about 6-7. I have a serious issue with both procrastination and laziness. I also have a bad habit of not brushing my teeth regularly. In fact there were some times I'd go over a week without brushing them if I wasn't leaving the house. This, along with my admittedly poor diet is why my teeth arn't in the best of shape... Trying to fix this though, and I've been making sure to brush both day and night.
procrastinator being my biggest one constantly thinking the worst outcome of a situation is another, but that's anxiety for you
