If you are CEO of your own company, your most important role is to drive revenue to your bottom line. To succeed in this role, you must understand that if you work an eight hour day, then you must spend half of each and every day prospecting for sales.
If you are a meeting or event planner, you have a big job. You may be hired from an outside source or you may work for the company having the event. Your job in planning a convention or meeting is to plan and coordinate everything from the venue of the event to the keynote speaker.
