The unexamined life is not worth living.
ὁ ἀνεξέταστος βίος οὐ βιωτὸς ἀνθρώπῳ
Socrates believed that philosophy – the love of wisdom – is the most important pursuit above all else.
For philosophers and martial artists alike, wisdom should be the highest pursuit: using good judgment; making correct decisions; practicing discernment; doing the right things.
The examined life is intrinsic to the pursuit of wisdom, as one attempts to fulfill the Delphic maxim, γνῶθι σεαυτόν: "Know Thyself."
Self-reflection requires putting aside one's excuses, personal bias, ego, assumptions, and preferences to come to terms with who we are and what we need to change, improve, or eliminate from our habits, attitudes, and thought patterns.
Friedrich Nietzsche explained, "the worst enemy you will meet will always be yourself." Resistance to change, personal pride, and the discomfort in challenging and improving yourself are opponents within us that we must overcome in order to truly find wisdom and live what Socrates calls "the examined life."
The first step is to understand you can do it.
