What is my "Ikigai" or my main purpose in life?

To promote the most important benefits of educating oneself in order for all of us to avoid staying so ignorant in our daily lives.
Teaching ESL to aspiring educators who could be able to create life-changing differences themselves had always been such a self-fulfilling activity and a fun job for me to do, so I never wanted anyone to just ignore their studies in the basic fundamentals of English, but I also proactively guide them all throughout their learning journeys without ever leaving them to correct all of their own mistakes while feeling so demotivated to not even have someone to teach them how they could learn from their mistakes.
We should always be playing the part of a "student" even if we have already completed our formal education, and if you are now a teacher of your own classes, then you still have so much to learn about your self-actualization and your real meaning to live your life.
