Getting Things Done - GTD

Take Care of Your Energy and Be More Productive This Summer
One of the factors that influence the most in your personal productivity is the energy you have when you need to face a task. It’s obvious that if you’re feeling tired, moody, distracted or grumpy, you won’t be capable of keeping the same level of attention to what you are doing and because of this you either will take longer to complete the task or the final result will be worse. But usually, both things will happen.
