Rands, in response to all the “learn to code” articles, suggests truly learning your own language:
Writing is the connective tissue that creates understanding. We, as social creatures, often better perform rituals to form understanding one on one, but good writing enables us to understand each other at scale.
More than any other hack, mastering language and communication will help you get things done. It will improve small things, like make meetings more efficient (or not necessary at all) and cut down on the amount of email you have to deal with. It will help you see the parts of an idea so you can thread them together. But ultimately it will build people’s trust in you. You’ll be given permission to do better things more often.
Learn to write and you will learn to connect the pieces that shape great ideas.
