Are you using the best pen for you? What about the best notebook? I come at this from the perspective of a writer, but the tools are anything that helps you to do the work. Ignoring our tools will only do us a disservice. However, spending too much time evaluating them takes away from the work.
It’s a difficult balance to find. Heck, I had the perfect “inexpensive-yet-good always in my pocket don’t even have to think about it” pen up until a couple of weeks ago when I encountered something I like even more. The danger comes when you spend so much time always seeking something better, that you don’t settle on good enough and get to work.
