Chances are good that, at some time in your life, you’ve taken a time management class, read about it in books, and tried to use an electronic or paper-based day planner to organize, prioritize and schedule your day. “Why, with this knowledge and these gadgets,” you may ask, “do I still feel like I can’t get everything done I need to?”

The answer is simple. Before you can even begin to manage time, you must learn what time is. A dictionary defines time as “the point or period at which things occur.” Put simply, time is when stuff happens.

There are two types of time: clock time and real time. In clock time, there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day and 365 days in a year. All time passes equally. When someone turns 50, they are exactly 50 years old, no more or no less.

Which time describes the world in which you really live, real time or clock time?

The reason time management gadgets and systems don’t work is that these systems are designed to manage clock time. Clock time is irrelevant. You don’t live in or even have access to clock time. You live in real time, a world in which all time flies when you are having fun or drags when you are doing your taxes.

The good news is that real time is mental. It exists between your ears. You create it. Anything you create, you can manage. It’s time to remove any self-sabotage or self-limitation you have around “not having enough time,” or today not being “the right time” to start a business or manage your current business properly.

There are only three ways to spend time: thoughts, conversations and actions. Regardless of the type of business you own, your work will be composed of those three items.

As an entrepreneur, you may be frequently interrupted or pulled in different directions. While you cannot eliminate interruptions, you do get a say on how much time you will spend on them and how much time you will spend on the thoughts, conversations and actions that will lead you to success.
