How to Use Less Complex Tools to Improve Your Productivity

I think Einstein was the source of something like that when he was talking about complexity. Like as complex as it needs to be, but no more. And then for years I've been kind of equating that to choosing apps like task managers. But I feel like there's another angle to this and say, figure out how complex you need it and get something slightly less complex. Particularly if you're using the complex tools and you feel like you're not getting your work done, try something slightly less. See how that works.
