When you're used to being in the public eye, if you've got a disease, you've got to own up to it. It's about being about it, not running from it.
Before you do anything, whatever it is, figure out who you are first.
Accept who you are and try and make the best of that.
Move every day. Like taking a shower and brushing your teeth. Make it a part of your everyday life.
You can never go more than three or four hours without having something to nibble on or eat - you have to graze all day long.
