Find ways to sustain and improve your mental health. The future will get only more stressful and the thing between your ears will largely determine if your life is well lived or not. So far I have seen three areas that you should really look into. Sleep, meditation and exercise. In that order. They all do one thing well and that is to reduce stress and increase your resistance to stress. All other areas in your life will improve, but it’s a slow process which results are only visible after roughly two months of consistent effort.
