One should be a student first and a teacher second.
A seasoned teacher teaches after first being taught by someone else or from life’s experiences. The knowledge that they gain over a duration of time can be shared after they’ve been able to apply the knowledge given.
Nothing can be poured out of an empty vessel. Many are teaching on topical matters that they have not yet been filled up enough with knowledge to teach.
The wiser individual will not shy away from being a student, because they understand that skyscraper potential needs a secure FOUNDATION in order to withstand the tests of time.
