The productivity paradox
Personal productivity is a mix of different techniques and strategies. You can pay attention to three things that affect your productivity: time, output, and quality.
Given the tasks you're doing, you'll want to get more work done in less time while keeping high quality.
Few people can find the best combination of the three variables, and each of those people has a different secret.
The book "Atomic Habits" is a good place to start learning about how to be more productive.
