Senior developer tip 4 out of 100. Learn how to touch type. It can double or even triple your productivity as a programmer. Oh dragos, but I spend most of my time thinking and designing and not coding. I'm a developer, not a typist. Look, even if you don't code all day, you are writing release notes, documentation and Jira tickets. Touch typing will make all those things faster, giving you even more time to think and design.
It also shows that you care about mastering your craft and your tools, such as your keyboard. If you want to improve your typing speed right now, I recommend websites like 10 Fast Fingers, Type Racer or Monkey Type. And if you really want to become faster, make sure you master keyboard shortcuts and hotkeys in your code editor of choice.
