What is something you could easily do but haven't out of habit?

Probably fix my desktop computer. It's been down since 2017, with a failing PSU, bad capacitors, and a bad chipset fan.

I already have all new replacement parts I need to fix it, for the third time no less, but I just haven't felt like outright doing it yet.

Honestly, I'll probably be more motivated to fix it if I get some sockets to install where the capacitors are, so I don't have to keep torturing the board with the soldering iron in the future.

I dunno, my 2 laptops have been good enough for me over the years since, maybe I'll fix the desktop one of these ~~days~~ years...

Fix a light that is hanging out of the wall because the asshats who built my house didn't put it in a box.

File organiztion on my desktop. It's a mess, but it's my mess and I pretty much know where everything is

Buying things on credit.

I think I get what you mean, but for anyone else reading: Get cash back rewards!
I use my credit card for literally every single purchase I would normally make, paying bills and all, and I get between 1.5%-3% back. Obviously you never let interest accrue you just pay it off right away, but every few months I get essentially free money, usually $200+!
- I do this, but recently had the realization that my small percentage of cash back is sourced from the fee the credit card company charges to the vendor. After this realization I now prefer to pay cash when dealing with small local businesses. I've even found a few places that will give you a discount for not using a credit card which is quite nice.
- Why are you making an "everyone should" thing out of it?

Honestly, pretty much everything I do is habit.

If I have to actually think about doing something, it's usually because something really bad just happened.

For a while, I thought the answer to this was writing a book I've been thinking about for a long time. Then, after seeming years of thinking about it, I went to write it down only to realize it's unwritable because of certain transitions that were not considered. Starting a week ago, the answer has become another writing project, but I'm not thinking about it that much anyways.

The only way to write a book is to write. Every day. Every day.
- i'm giving you a longing look 👀 everyday, you write the book?
- No. Take breaks wheb you see fit, just return to it.

Die.

I've got a habit of living. Nothing more, really, it's just a habit.

Almost anything I claim to want to do.

Get a new computer. My ageing HDD's experience this intermittent issue with corruption which sometimes affects entire folders, typically larger ones which contain games. The HDD which stores Windows is also getting the same thing although not as bad. I'm also having issues with RAM and overall it'd be less hassle to just replace the whole computer rather than buying parts and fixing it.
Get a new monitor even though I just set a brand new one up yesterday after I ordered it from Amazon. I can definitely notice the difference between 350 nits (old) and 250 nits (new) even though other people can't seem to notice any difference in the brightness

Currently, plug in my phone to my laptop and organize all the loose audio files on my SD card. I have a lot of organized ones already, but probably more unorganized out of the over 500 files than organized. Would just take a while of me sitting down and working instead of feeling daunted by the task.

I know I was planning to do this for a year.. finally did it, but since then my collection has tripled and its all worthless now. so I just embrace the chaos.
Same here. I've been meaning to get the photos off of my phone so I can install grapheneos for over a year now, and I just haven't.

Listen to the call of the void...

Numerous things. But, because of the straining amount of work I do at even 4 days (the place I work at sucks balls). I can't mentally attune myself or even physically attune myself into doing things I ideally want to do. I've gone into a bit of my routine. I could play a new game. I could watch a movie or a show. I could spend time in my living room with no tech in it. But I just end up not doing it.

Drink coffee. I grew up drinking tea and I love drinking tea, and there's a place where I live that makes exceptionally good loose leaf, but coffee is way more commonly drunk here but I've never thought to try it.
