It’s mind boggling how different the modern concept of work is from how it was for 99.9% of human existence.
I’m sure the hyper-optimization, hyper-specialization, the alienation, and the constant flux of modern work contributes greatly to the problems we are experiencing.
Even when there was no “adventurous alternative”, work was a lot more grounded in society and had a lot more downtime at pretty much any point in history.
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).
