Myself, I struggled with organization for a long time.
Now I keep things simple as possible:
* Heavy use of Notes and Calendar, so that everything stays synced across devices. Using hashtags helps me find stuff, rather than trying to keep things organized in folders.
* Planning & vision board type stuff gets done in FreeForm. Organizing things spatially helps me know where to find and put stuff.
There are more powerful tools out there... But keeping things simple, consistent, interoperable and in one cloud is what I personally prefer.
> How do you keep track of tasks, todos etc
I have a pinned Note which I use every day for minor tasks. If something is critical then I either try to do it immediately, or add it as an event in Calendar with multiple alarms.

Body doubling can be effective when you're really stuck. There are a lot of free options for this, but if you want to try a session just to see what it's like I recommend Flow Club [0].
And, maybe weirder again, niacinamide. A high dose of this wipes out brain fog (for me) for like an hour or two. It's very cheap and pretty safe so I recommend looking into it.
