Mind fitness is as equally important as physical fitness. Ever heard of the famous adage ” what you think is what you are”?
Based on the original article, personal development focuses on three aspects: mind, body and soul.
You can’t say you have promoted overall fitness if you missed out on focusing on your mind and soul. When you focus on being mentally fit, your body can also benefit from it as well. I consider number 1 as an effective way of promoting mind fitness.
One of the first things one think of when talking about stimulating the mind is reading. It doesn´t necessarily have to be books, but reading on the whole is stimulating the mind. It also develop ones feeling for language, and developing the language makes one grow as a human. One can assimilate broader and deeper texts.
