Time vs Energy
Time and energy are the most confused topics when it comes to personal productivity. We often hear someone say "I don't have time to go to the gym" or "I don't have time to read books". Very often it's not an issue of time, but rather of energy.
Time management and Energy management are two different disciplines. Understanding the difference helps you recognize when you actually have the time but lack the energy, and vice versa. This awareness is the first step to becoming more productive.
