got to give a four. since like It our not I've got to live with myself. so  might as well learn from myself the best i can. in any way from the mistakes I have made, to good decisions.  each step may help me to be the best me I can. maybe I am not great but try to get by in this world.

This may seem like a selfish thing to say that I am my own greatest teacher. However, I am the one who made the mistakes in my life, and I am the one who had to learn from them. I am the one who has had to go through the experiences in my life. And I am the one who is still learning from them. Not to say that I haven't had help along the way, because yes, I was influenced by many great people to be what I am. So I guess I could say I've also had some good "teacher's assistants" too.

no really, I mean this in all seriousness - I did teach myself much about what I know - I bet people who grew up as only children would understand what I mean
