|DIY can be hard to handle.|
Diet: Eat things that are good and that you enjoy. Don't deny yourself treats but eat and drink and be happy.
Diplomacy: Live a sensible life, be out there but don't be far out. Respect your fellow humans and travelers. Don't be a shouty, moany arse, don't be a Tory, live and let live and do a bit of exercise now and then. Take what you need not all that you might want.
Doze. Get a good night's sleep, don't overdo things, be measured, have a nap if you need a nap. Take a day off now and then wearing loose and comfortable clothing.
*For clarity and truth, we don't actually use three Ds or anything like that, we're not weird. This is just made up stuff, fiction if you will, with a tiny sprinkling of reality now and then.
