The Seven part Recipe for Good Mental Health

EXERCISE
HYDRATE
EAT
SLEEP/REST
MEDICATION(S)
MUSIC
JOURNAL

This list is not an exhaustive list, but they do make up key components for good mental health...Let's look at the first one.

EXERCISE
Personally, I try to do a couple types of exercise either at least a couple times per week to some every day. For example, I've been playing tennis my whole life,  but I am 40 now, so I can at most play tennis just about 2-3 times per week, before my feet start to get sore. Other types of exercise, like walking, which I do, almost every day for 20-30 minutes. Anything to get the heart rate up was what my doctor told me. There are many types of exercise one can try. Stretching, yoga, basketball, table tennis (one of the best for mental health), biking, walking, surfing, swimming. Be adventurous and keep an open mind. Do activities that are fun, safe and repeatable. You want to establish a new routine or at least be open to trying new things.

HYDRATE
I am still trying to master this one, as some fluids are better at hydrating the body than others.
