Wish more people understood this. We spend a lot of time changing tools and it's as bad or worse than context switching. Every tool has a learning curve and if you keep switching tools, you are always stuck in the initial part of the learning curve. I think this greatly hampers learning.

Hyper productive people who I have seen as well exhibit similar behavior. They just stick to tools that they are comfortable with and focus on the task at hand.

Also another anecdotal observation - some of the best chefs I have seen don't usually switch tools, be it knives or utensils. They mostly stick to the same tools for a very long time. So they invest in tools that can last and can be maintained. Not sure if the analogy holds true in other fields as well.

Pen and paper as a form of expressing streaming thoughts works for me as well. It also works because I write a lot slower than I can type. Ever since I have started writing pretty consistently over the last 4-5 months, the format of pen and paper doesn't really matter to me. I can write using any pen and any paper. I have found fountain pens to be particularly cumbersome to maintain and also my kids just take whatever pen is on my table and run off. As a result I just have a 100s pack of the same cheap pen. One went missing, pick up another one.
