Have you thought about that? I know it from my own experience that it's true.
Learn to prioritize your day, your tasks, your everything and you'll see that you'll be able to get the important things done fast first.
Every morning ask yourself the following question: What is the One Thing I should Do Today that by doing it everything else will be easier or unnecessary? I greatly recommend that you read "The ONE Thing" by Gary Keller & Jay Papasan, it will open your eyes and help you become more productive.
As the authors say: " Start thinking Big by going small and focusing on your ONE Thing today!"
