There is a habit that wastes more time than anything else when using Claude.

Save this :)

Writing the same instructions over and over again.

Every session, you re-explain your role. You re-describe your writing style. You re-state your formatting preferences. You re-paste your company context. You re-specify what you want the output to look like.

Then you do it again tomorrow. And the day after that. And the day after that.
