Time management starts with the commitment to change. Time management is easy as long as you commit to action. You can train others and improve your own time management through better planning, prioritizing, delegating, controlling your environment, understanding yourself and identifying what you will change about your habits, routines and attitude.
The key to successful time management is planning and then protecting the planned time. If you plan what to do and when, and then stick to it, then you will have time. This involves conditioning, or re-conditioning your environment. For people who have demands placed on them by others, particularly other departments, managers, customers, etc, time management requires diplomatically managing the expectations of others. Time management is chiefly about conditioning your environment, rather than allowing your environment to condition you. If you tolerate, and accept without question, the interruptions and demands of others then you effectively encourage these time management pressures to continue.
