Good post. I also think the last point on healthy eating and exercise is very important. I remember when I was back on diet and in a good shape I could get away with less sleep and my mind was fresher and overall I felt good all the time. Feeling good brings positive thinking and at the end productivity in all aspect of ones life. This together with the extra time you get (sleeping 6 hours instead of 7, not feeling drowsy for 40 minutes after lunch, etc.) makes a huge difference. That's why I am also getting back to diet this year.

And I want to try one more thing that probably falls into the mental health category: meditation.
