Einstein said that time is just an illusion, everything is happening simultaneously, whatever you want in the future already exists. If you create your day in advance by thinking the way you want it to go you will create your life intentionally.
How often do you waste time worrying about how much time you don’t have? Notice yourself doing this and step out of this unproductive nonconstructive way of thinking. You are not doing yourself any favours by using your energy for such thoughts, you are simply encouraging the minutes to pass you by. Grab hold of the current reality and the moment that is around you, grasp it and be at your fullest potential.
Set short mile stones and goals for your future 15 minutes (at a time), remember the longest journey begins with the smallest steps.
