You may be the best baker in the world. But if can’t talk about why your bread is better, how will you charge a premium for it?
Talking to people about what you do is as important as actually doing your thing.
If you can explain why your work is valuable, if you can explain how people should use what you made, your customers will get more value.
Would you gain more from learning to talk about your bread than you would from making it taste better?
