Uncomfortable situations and their role in life

In some cold countries, parents douse their babies in ice cold water, ignoring their pleading cries, to get them comfortable with low temperatures. 

A close contact with manageable hardships makes us resilient, and as time goes by, we toughen up, gain experience and start maneuvering through them with relative ease.
We begin to feel relaxed in the midst of chaos and adversity, because we have conditioned our bodies, and minds to handle difficulty.
Developing muscles works in the same way. During the first couple of months, we feel winded after lifting a couple of dumbbells. In time, the same weight feels lighter.

Gradual exposure to difficult situations allow us to get our body and brain attuned to hardships and become comfortable with discomfort.

Sheltered upbringing leads to a hard life.  

In our times, life become comparatively easier, and the necessity to willingly expose ourselves to difficult situations become of a great import to the development of our ability to navigate the vagaries of life. 

It could range from talking to random strangers, to trying activities tha are new to us, to learning new skills at an advanced age.

The man you are seeking is always on the other side of difficulties.
