Rant

This feels odd to explain, but there's 4 main scenarios:

1. There's too much stuff I have to do

I just get overwhelmed. I don't know where to start. What do I do first? I must start right away, but how?
If I pick one thing to do first, the knowledge of other ones keeps taking my focus, and I just end up doing nothing and panicking.

2. There's just something I have to do

Absolutely anything will suddenly seem interesting. I am supposed to study math?
How about getting back to Meteor LRPT reception? What about checking out the TETRA signal in your location? Installing Proxmox on a laptop, sure thing. Yes, now is the time to read datasheet of NTAG NFC tags and try out manually sending the commands in hexadecimal. What's math, let's start studying railroad regulations. Meshcore? Hell yeah, let's join the network.
etc...

3. There's nothing to do

Sounds like the time for my interests. But now, nothing comes to mind. Nothing sounds interesting. Absolutely nothing. I don't want to waste time, yet at the same time I don't want to... anything.
Even just getting dressed up feels like dragging my soul across sharp rocks.

4. Deadline is approaching FAAAAAAAST

Oddly, in some way the best scenario. I can finally get myself to be productive, and it even feels good. I see what I did, I see I spent the time well, I can focus.
One good example, an assignment I managed to do shortly before deadline. I put in 16 hours at once, only leaving to the toilet. I finished it at 4am before waking up at 7am, yet, I felt satisfied.
However, one "bad" thing that can happen here is "deadline extended by one week" if I cannot manage it. Suddenly, I loose that feeling of urgency, and slip back into scenario 2.

Bonus: Everything is a distraction.

I occasionally see people recommend putting your phone away, disabling notifications, etc...
Cool, cool.
However, I often get distracted by things like... the pen and paper. Look at that beautiful ink being transferred to the sheet of paper.
But hell, you can remove any physical objects, but you can't remove thoughts. I am listening, I am focused, and oh fuck, there goes a 10 minute imaginary conversation.
OK, I need to do better. Focus, listen, read, think, focus, listen, read,... great, I am focusing on focusing itself.

And lastly, ever heard of /dev/null? My brain pipes to it fairly often. Past 5 minutes? Never heard of them.
I can re-read something 3 times, and just immediately forget what the hell that was.
I can think of something, make the slightest physical movement, and it's gone.
I can listen to someone, process it, answer, immediately forget what I just answered to.
