A book I used to give all new managers is titled
The First 90 Days by Michael Watkins.
New managers are very gung ho and want to make changes early on.
Doing so before understanding their department, it's people and culture, and the company can result in errors that damage the new manager's reputation. Especially if a decision has to be reversed (as Doge has had to do repeatedly).
So Watkins' advice is to spend the first 90 days gaining an understanding of the environment and building good relationships with the immediate team and company resource departments.
Elon could benefit from this book. Not only is he trying to fix stuff that might not be broken, he's ****ing up stuff that's probably not broken.
