The key is to stay positively focused on what you can control - easier if you take control of your own frame of mind first.
GET MOVING before worry takes hold. Try a quick burst of vigorous exercise - eg, running up and down stairs. This diverts your attention and releases tension.
EAT STRATEGICALLY. Start the day with serotonin-boosting foods such as a banana or grain cereal. Make lunch a high-protein energiser, dinner a plateful of relaxing carbohydrates.
REACTIVATE positive emotional memories. Keep reminders such as significant photos or trophies on your desk or dashboard.
KEEP LAUGHING. Humour and fun are the best and cheapest antidotes to stress.
