Optimism will keep you young and beautiful.
Wear a little make-up and a lot of confidence. Men always find this attractive. Never be afraid to shine.
Drink 4 bottles of water a day and a nice glass of Cabernet in the evening. It helps you get the sleep you need.
Eat three meals a day. Skip one and you'll binge later. If you want to eat something you consider a cheat, make it count. Go for a fabulous dark chocolate truffle instead of a cheap candy bar. Perfect example of how to send positive messages to yourself. Make a conscious effort to do so.
Walk at least 30 minutes, preferably at lunchtime. You'll be glad you took the time off work and your skin will have a great glow in the afternoon. It also reduces the need to powder your nose for a late day meeting.
Never pay retail. Buy classic suits and you'll never be afraid to look back in your photo albums. And for that matter, always buy good underwear. Keeping your most beautiful items closest to your skin tells your body you love it and intend to care for the gift G-d gave you to house your soul.
Sage advice. You sound like you're one classy gal.
