I want to try to skip unhealthy stuff like candy, coda etc and try to live as healthy as possible in december month. Reddit, tell me some ways I can improve my health during this month :)

Examples:

• exercise every day (Any specific good exercises?)
• 6 fruits every day
• vitamin pills to make sure I get all my vitamins
• Go to bed early, to get a steady sleep cycle all 7 weekdays.

Anything more I can do?
