Here’s a trick that works for me (who mainly have trouble getting started with things).
Decide that you only need to do the thing for 10 minutes. Set a timer for 10 minutes and get started. Then when the timer rings you’ve gotten going and will likely want to continue (forever).
Economists refuse to accept that their subject is really just sociology. They like to imagine it being like physics, where study of reality leads to underlying mathematical truths to extrapolate from. Not a big messy subject where you can’t be certain of anything.
What makes it even more freaky is that many of the subjects being studied know they are playing a game. So in many ways economy is more like the evolving metagame of competitive sports, where hardcore nerds constantly try to game the system and outplay each other, and what was a solid strategy last month doesn’t work anymore, even if the rules are the same.
