The healthier you are in life, the longer you'll be able to enjoy it. Focusing on your health will immediately improve your productivity, mood, relationships, and many other parts of your life. Physical well being is an obvious benefit but training also sharpens your mental clarity. You'll be able to make smarter decisions throughout your day to day.
FIND THE SYSTEM. REACH THE GOAL.
When most people think of improving their health, there's always one or two things that immediately come to mind that they would change. If you embrace change, you will grow and evolve physically and mentally. You will build layers and layers of learned lessons that propel you forward into your next challenge. If you avoid change, you will remain the same. It'll be a never ending loop that keeps you moving but gets you nowhere.
