What makes a teacher great?
I am not saying you need just real life experiences but reading books helps as well.
Reading books like think rich and grow rich gives you a perspective where you can use it in the real world.
Mostly learning comes from experimenting, we all make mistakes, that is if we learn from them.
Also listening to podcasts helps which I listen to the likes of Tai Lopez as he offers his perspectives and experiences as he has some credibility in his words.
So basically, I am always learning, listening to older people and younger people because who knows… They have different experiences or different worlds that they share with us through podcasts or books or even real life through words. I find when someone offers their opinions or teaches you in person it is easier to absorb their experiences or perspectives.
