We have all done it at one time or other. We put off our exercise routine until tomorrow; we continually delay finishing that project or starting that business.
We all get 7 days a week, 168 hours within those 7 days. This cannot be increased or changed in any way. What we can change, improve, and manage, is ourselves.
Time management is the meticulous way of performing tasks in the available number of hours. It has become a necessity as a person ends up performing many roles.
