Most people's productivity habits are based on guesswork, but it's possible to find your peak productive environment by tracking how you spend your time. RescueTime is a tool that tracks where you spend your time and provides data on your productivity, allowing you to see when you're most productive, what activities are distracting you the most, and how different variables affect your output. By using RescueTime, you can identify your current peak hours, conduct experiments to optimize them, and make data-driven decisions about your work environment and schedule. For example, an experiment might involve working from a coffee shop for a week to see if it boosts productivity. By tracking your time and productivity, you can find the most productive times of day and environments that work best for you.
