It’s easy to hear that you can speed up your work with tools like TextExpander or Keyboard Maestro and then either feel overwhelmed with trying to learn them or just find that you spend so much time playing that you don’t write enough.
Take on one new piece of software at a time. When it becomes like breathing, then try the next one.
And for each you try, don’t study them. Read the examples of what they can do, pick one that sounds useful to you, use that. Nothing else.
It sounds wrong: you spend a tonne of money and you’re only using it for this one piddly thing? But studying software doesn’t work. Needing it for a particular job does. When you need the software to do more, use it for more. You learn it because you’re actively using it for a purpose, you absorb it because it makes sense to you.
And remember above all else: using software is a lot easier than writing.
