When we complete a task, we stop thinking about it. When we start a task and get interrupted before we finish, it remains active in our minds while it is in that undone state. Three simple rules of work are:
1.) If it takes less than five minutes, do it right now.
2.) When you start something, finish it. (If the task is too massive, break it into smaller tasks and do them.)
3.) Never ever, ever, ever multitask.
Harness all of your energy and focus on one task at a time and you’ll do more work at a higher quality than you ever thought possible.
