On what subject(s) are you an authority?

There are many people in the world who consider themselves experts in their field. But in my view, if there is anyone who is an expert then it is God. I do not consider myself an expert in any subject/subjects. Because I believe in learning. There is no end to learning any subject. When we consider ourselves experts, then we are not able to learn anything new. And we are deprived of further knowledge of that subject.

I have interest and experience in many things like cooking, painting, embroidery, writing bhajans, poetry, interior decoration etc. But I do not consider myself an expert. Because I feel that the day I consider myself an expert, a feeling of ego will develop within me.so no authority no proud.
