I keep a running to-do list, and when I have time, I consult the list and get things done. Sometimes it seems strange to complete a task not due for a long time, but in the end, I never regret completing that chore when the right time and energy is there. Time and again, the day arrives when the task completion is required, and I am so happy I got it done ahead of time.
To keep that running to-do list truly heps you to match good energy with tasks, and when you complete those tasks with good energy, the task completion is usually better. So on this gray, rainy day, I'll consult the list and complete a number of not-too-enticing tasks. The next time the sun is shining, I'll be happy that this tiresome tasks are done.
