AFoxImmortal I have a very strong connection to your second bullet point. Just earlier I was looking through my notifications and the author who I gave title suggestions to (they asked for it in the forums) said something along the lines of, 'Wow you guessed my book's plot just from the tags/synopsis'.
It wasn't a long rant, maybe, but I ended up writing so much. It went from title giving to me deeply deciphering the story/characters. (´ー∀ー`)
But other than that, they may not be old habits but things I'm trying to stop doing:
-Hoarding: I'm a hoarder for random things. You ever buy earbuds and it comes with extra little rubber bits to change them to fit your ear? Well, I have a TON on those. I went to a thrift store and bought 3 music boxes. One was a little globe but I don't know why I bought 3.
-Staying up all night: This, this has become an issue. I stayed up for about 30+ hours before passing out once. This quarantine has really messed up my sleep schedule. I need to fix it but it's hard. At night I don't really feel sleepy so I just end up doing random things. Typing chapters for books/ideas I might never publish, re-reading said chapters, drawing, etc.
-Coffee: I guess you could call it an old habit but before quarantine I drank a lot of coffee, almost everyday previously. Just recently I bought a lot of coffee because I thought, 'Why not?'. Then I moved onto that coffee trend nowadays. The one where you whip the coffee until it's fluffy-ish and mix it with heavy cream/milk/almond milk etc.
Just me things but, looking back at it, I've once again written too much. I'm a lazy person so I don't even want to go through and delete things. Here, take my brain barf of like, five minutes.
