There’s an old Latin saying, “Qui docet, discit.” (He who teaches, learns.)
The best teachers don’t preach to others, they learn from others.
You don’t need to wait until you have a teaching certificate, a particular degree, enough gray hair, or a 100k followers to pass on knowledge and skills or inspire others.
You know more than you think you know; you bring your own unique set of skills, point of view, and life experiences to the table.
Don’t worry about not having all of the answers, you never will and neither will anyone else. Instead, approach each day with the question, “I don’t know but I’ll find out.” Then share what you learn.
