I am unable to understand some things in life, not at an intellectual level but on the sensations plan.

The first one is boredom. Life is so rich and colorful that I cannot imagine how it is to feel bored. The second one is how routine is often viewed with disdain.

However, a shift in perspective can be operated even here. I find that PTSD is relieved when we take care of ourselves with loving kindness. I find that having a routine is part of that. I like the certainty of a routine. It helps me to deal better with the uncertainty of life.
