What Makes You Productive?
It's not bouncing around, trying out new tools and techniques.
It's not constantly hacking in an effort to streamline or maximize your productivity (whatever that means).
What makes you productive is getting your hands dirty and doing the work. Completing that work to the best of your ability. And doing it with the tools at hand.
That's the way it is. That's the way it's always been. As I've written before, your most powerful tool for productivity is you. Your knowledge. Your focus. Your discipline and persistence. Tools can augment that, but they won't replace any or all of that.
As someone wrote:
Can you imagine how good I’d be at the old things if I would stop constantly moving to the new things?
Stick with the old things. Get stuff done.
