The ultimate feeling of satisfaction

is to be completely focused on yourself,
treating yourself like a work of art.
This is also the highest return on investment.
People like this
absolutely won't waste energy on internal conflicts,
because they hardly pay attention to anyone else.
From skin to physique,
from diet to brain,
they are constantly refining themselves every day.
They don't need to form relationships with anyone,
don't need anyone's approval,
and care even less about others' negative comments.
When you don't care and don't need these things,
you have no worries.
When you don't need external validation,
and can live a fulfilling life,
you will feel incredibly great.
