Are you disorganized?  Do you need help meeting your goals?  I recommend these books:
I. Stephen Covey, The 7 Habits of Highly Effective People.
    p. 60 Get personally involved in all material you read; read as if you are going to teach it within 48 hours.  This also helps you avoid wasting time, by actively learning the material.
    p.98- Begin with the end (goal) in mind.  This helps you focus and manage your time around what is important to you: your goal.
    p. 151 Time Management Matrix: Activities fall into one of 4 categories
        Urgent and Important: crises, pressing problems, deadline driven projects
        Urgent and not important: interruptions, some mail, some meetings...

        Not urgent and important: relationships, planning, recreation, building relationships, recognizing new opportunities...
        Not urgent and not important: busy work, some phone calls, some mail...

II. Hyrum W. Smith, The 10 Natural Laws of Successful Time and Life Management.
This books helps you to gain control over your life by gaining control of your time.  Naturally, there are some things we can’t control, but there are significant tips here for how to control what you can.  I think the book also helps us see how our behavior may be wasting other people’s time, so we may learn how to make the most out of the time we request from other people.

    Law 1: You control your life by controlling your time.
    Law 2: Your governing values are the foundation of personal success and fulfillment.
    Law 3: When your daily activities reflect your governing values, you experience inner peace.
    Law 4: To reach any significant goal, you must leave your comfort zone.
    Law 5: Consistent daily planning leverages time and increases focus.

Time Robbers (pp. 30-45)

    Waiting for answers
    Unclear job definition
    Unnecessary meetings
    too much work
    poor communication
    shifting priorities
    equipment failure
    disorganized boss
    red tape
    conflicting priorities
    low community morale
    untrained staff
    peer/staff demands
    lack of authority
    mistakes of others
    revised deadlines

II. Self-Inflicted Time Robbers
    failure to delegate
    poor attitude
    personal disorganization
    absentmindedness
    failure to listen
    indecision
    socializing
    fatigue
    lack of self-discipline
    leaving tasks unfinished
    paper shuffling
    procrastination
    outside activities
    cluttered workspace
    unclear personal goals
    perfectionism
    poor planning
    preoccupation
    attempting too much

Of all of these, the most commonly experienced time robbers are:
    1. interruptions
        Unnecessary Interruptions: “someone drops in unannounced or calls on the phone, mistakenly assuming that you care, that you have the required information, or that you are responsible.  If none of these is true, then this is an unnecessary intrusion....This interruptions is to be avoided or terminated quickly.
        Necessary Interruptions “are those about which you do care, for which you do have information, or are responsible.  A necessary interruption has value, and you should handle it at once, unless it is untimely.”
        Untimely Interruptions “are necessary, but come at an inconvenient or inappropriate time.  These should be rescheduled to a more suitable time.”
    2. procrastination
        --set a deadline and stick to it.
        --divide large projects into smaller units
    3. shifting priorities
    4. poor planning: If you fail to plan, you plan to fail”
    5. waiting for answers: request a time-frame for an expected answer; call the person if the answer doesn’t come in that time-frame and explain your need for getting the answer.  Ask what you can do you help out the situation.
