This is a great one sheet on how you can improve yourself by doing little simple things every day! There are certain tips I am more partial to than others but everyone's bodies are different. For me, eating five small meals a day doesn't work but for many people, it does. Drinking more water however, is beneficial to everyone.

The point being, most of these tips are universal but if you are unsure, do the research or experiment with yourself and see what works for you! Good luck!
