How can I get more things done quickly?

Outline speedrunning

From https://learnhowtolearn.org/how-to-build-extremely-quickly/:

Do “outline speedrunning”: Recursively outline an MVP, speedrun filling it in, and only then go back and perfect.

Tracer bullets

From https://wiki.c2.com/?TracerBullets:

a method of software engineering that is likened to firing a machine gun at night. You can either know exactly where you are, where the target is and do the the maths to work out how to point it and hope you’re right… or you can load every other bullet with tracer (which glows in the dark) and then just turn the outgoing line of bullets (which you can now see) onto the target.

Programming-wise, it involves short cycles of development, then delivery and asking the customer if it’s closer or further from what they think the target is… rather than finding out right at the end that you’ve misunderstood something.

I don’t think that tracer bullets are just about making adjustments to requirements. Aren’t they about making invisible things visible - so that you can handle them?

Eliminate low velocity stuff

From https://longform.asmartbear.com/double-your-productivity/:

To average 60 mph you need to travel the whole 60 miles in a single hour. But it’s already been an hour! Even if you went 1000 mph during the second half, it would have taken just over an hour to complete the 60 miles, therefore your average is still less than 60 mph.

It’s amazing how periods of low velocity wash away gains of high velocity. In the puzzle, if you doubled your speed in the second half it would only increase your trip average from 30 to 40 mph. If you quadrupled your speed in the second half, your trip average would still be only 48 mph.

Once you realize that the low-velocity stuff is responsible for most of the drag on your productivity, you realize that the thing to do is eliminate the low velocity stuff.
