Why am I so disorganized? please help?

um okay, i know i have a slight problem with organizing stuff and well for one my room is mess like all the time i mean i clean it, i really do make an effort and clean it during the weekends or halfway through the week but then 3 days or a week later it's back to the messy state it was before. I used to be really neat till i was about in year 10 but now, im like boosh and it's not only that today i don't know what on earth happened but you know on those escalator thingys, well instead of going on the up ones(the ones that go up) i went on the down ones to go up, i was looking at them and saw them going down but my brain did not click (so embarrassing) then it nearly happened again i mean sure im air headed a lot of times but this incident was ridiculous is there something wrong with my brain? I mean I don’t know why im like this, i sometimes hardly pay attention to my surroundings. Like if im walking, if i set my mid on getting somewhere it's like my mind subconsciously turns off everything surrounding me, all im focused on is my destination nothing else. That’s kinda weird right? sorry just a random thing u know like when u r typing and well i don’t know why but i usually type some of my word like (this is an example) "thign...thta....clikc..knwo" or at times "iright....htink etc" ya know? mixin up either the front two letters of a word or last two at times the middle ones but mostly it's the last two letters. I'm sure this is just a stupid thingy but i just wanted to ask, to find out if it's normal, well it's not normal but if it's something to worry about or just... i dont know a random thin
