I found a interesting quote in this post.

I believe if we love something and have fun, we tend to self teach and learn at a rapid rate. I also consider confusion a starting state for learning. It opens us to new patterns emerging. - Author: Todd Rice

Is it necessary to insert an "as" into "consider confusion a starting state" which produces "consider confusion as a starting state"?

or thanks to @TrevorD

insert an "to be" into "consider confusion a starting state" which produces "consider confusion to be a starting state"?

The key is to insert something, in case some one has unclear pronunciation, low voice.
