Task paralysis is the state where you know exactly what needs doing, you have time to do it, and you cannot begin any of it. It is not the same as procrastination, because there is no pleasant alternative you are choosing instead. You are frozen between options, usually doing nothing you enjoy either.
The way out is not a better plan. Planning is more deciding, and deciding is the thing that has jammed. What helps is making the next action so small that it does not require a decision.
The next ten minutes
Choose
Pick anything, badly. Which task you choose matters far less than choosing one. Two roughly equal options usually are roughly equal.
Cut it down
Cut it until it is almost insultingly small. Not do the taxes. Open the folder. Not call the landlord. Find the number.
Do only that
If momentum arrives, use it. If it does not, you have still moved.
Before you stop
Write down where you stopped, in one line, so returning does not mean reconstructing.
Why choosing is the hard part
When several things are all somewhat urgent and none has an obvious first step, every one of them costs energy to evaluate. Look at a list of nine of those and you can spend twenty minutes deciding and finish with nothing done and less capacity than you started with.
This is why a long list makes paralysis worse rather than better. The fix is to look at one thing, not to see everything more clearly.
Lower the bar rather than raising the pressure
The instinct is to increase stakes: promise yourself a deadline, imagine the consequences. That reliably raises the wall rather than lowering it, because the problem was never that you did not care enough.
Making the first action smaller works. Making the consequences larger does not, and usually adds dread to a task that already had plenty.
If nothing moves today
Then nothing moved today, and the tasks are exactly where they were, indifferent to it. What matters is that tomorrow does not start from zero, which is entirely about whether you left yourself a note about where you stopped.
More on that in picking something back up after abandoning it.
