Manage your time well to be effective

Dispose of your time in fairly large chunks.
For example, you will be more productive if you dedicate six straight hours to handling your monthly report than writing it in bits for 30 minutes daily.

Understand the achievements that are expected of you and the people you work with.
Have discussions with others and give instructions on tasks that require a reasonable amount of time.

Identify and eliminate the things that need not be done at all.
Eliminate items that are a total waste of time without any results. For example, you could decide to eliminate the countless speeches, dinners, committee memberships, and directorships that take an excessive toll on your time.

Identify the activities on your time log which could be handled by somebody else just as well, if not better.
For example, you could send one of your competent subordinates to represent you and your organization during networking events.

Ask others what you do to waste their time without contributing to their effectiveness.
For example, unnecessary meetings could be a time-waster for your colleagues, collaborators and subordinates.

Focus on the results and performance of the goals of the entire organization.
Set aside time to direct your vision from work to results.

Keep your time record and evaluate it monthly.
This will help you determine where you actually spend most of your time and you can, in turn, make adjustments accordingly.
