There is no doubt that your body and mind are intricately connected. When you feel good in body you often feel good in mind and vice versa. The same is true when you are not feeling very well. It’s difficult to feel good in your body if your mind is in pain.
The moral of this quote: Take care of both. If you want to change your body; you need to pay attention to your mind, too. If you want to change your mind; your body will play an important role. Never neglect any part of yourself, especially if you are looking to make meaningful change.
