It is said that the human being is a creature of habit. The word “habit” is derived from a root word meaning what one wears.
So, one can imagine that as one carries out the daily practices of meditation, physical exercise and reflection, one builds a protective garb around oneself. This comes in handy when dealing with real life problems.
The stoics advocated the practice of thinking about all the ways things can go wrong. In mentally thinking of all the ways things can go wrong, one can prepare oneself mentally for worst case scenarios. One can even mentally prepare some measures to address such scenarios.
Similarly, exercising one’s body and eating healthy foods on a daily basis also prepares one to face any potential issues later in life.
