Jenna asks, "Lately, I have been tired at work and cannot focus during meetings. Do you have any tips on how I can get back into the grove of things?"

Try changing your selection of food and drink items. Here are some tips:

• Avoid foods that are full of carbohydrates and really filling. Heavy meals will cause you to feel tired.

• Avoid extremely hot or cold beverages just before your meeting. Cold constricts the muscles; heat expands them. Both cause problems when speaking.

• Be sure to get your rest. If you stayed up all night tossing and turning because you were thinking about your big meeting - try taking a brief nap about an hour beforehand.

Follow these tips to feel rejuvenated and alert at your next meeting.
