"I don't, generally, think in words" is not the same as "I don't think in words".
Like I already said, if thought was exclusively in words for humans, humans wouldn't have the "It's on the tip of my tongue" problem. It's blindingly obvious that thought does not occur exclusively with words.
Don't worry, no one does.
That's why it is so common for people to forget a specific word they want to use ("it's on the tip of my tongue").
If we thought in words that will never happen.
