#9 When failure becomes a necessity.
Lack of education.
You cannot do much carpentry with bare hands and you cannot do much thinking with a bare mind. We all need to cultivate our minds with what can help us progress. We need to keep developing our mental capabilities and capacity.
Education is not about knowledge but the use of knowledge gained. Knowledge is not power on its own but potential power. A graduate could have knowledge but not education. Educated people therefore use the knowledge gained to achieve success.
Self gained education is the best education. The education you earn from your parents, from reading, from your elder brother, from observation and experience. Learn to always seek, gain and use the education gained to succeed or else failure will be a necessity in life. Remember, we are not paid for what we know but for the use of what we know.
