Filling time efficiently is the goal of Time Management. As you become proficient at this you will accomplish your daily tasks with ease and you will feel good about yourself.  The problem is not usually about having too much too do, or too little time, but one of management.  Lord Chesterfield said:

"The less one has to do, the less time one finds to do it in."

It will take some work, and you might have to change your habits until your everyday lifestyle incorporates time-saving ideas until time becomes a tool for your own use.  Take the time now to give yourself more time for the rest of your life.  You want to succeed and part of that success will depend on how well you manage your time.  For the most part, you are completely responsible for how YOUR allotment of 24 hours is spent each day.  It is up to you to shift your habits to satisfy the requirements to meet your goals.  Anyone is any situation--no matter how chaotic--can be organized if the desire and the will is there!
