To be comfortable with others, you need to be comfortable with yourself first. Often the real solitude is not the physical one but the inner one. You can feel alone even if you have friends. In fact you can also have many companies, but if these don’t make you feel good, it’s better to be alone. In fact we often feel bad because the best part of our soul is torn off us while we see our worst side growing inside us. In these cases it is worthwhile to take a period of solitude and reorganize our soul, which can also feel tired of the presence with the everyday world.
The periods of introspection are almost always considered sad and depressing and are not addressed, continuing their hectic life with the illusion that things can improve.
