Today, push yourself to complete your tasks or your assignments in much shorter time than you would usually allow yourself.
While you are at it, notice how much time you lose worrying that you won’t make the deadline. Notice the moments in which you prioritize stuff that seems urgent but isn't really important. Choose to not give power to worrying thoughts and distractions and instead be relaxed, present and simply do what is essential for your day. Your efforts will result in more time. Time you can spend on yourself.
