When you think with words, you can express what you think with those words only. To think with ideas is to be able to put the same idea in many kinds of words. The words can also be of different languages, if you happen to know more than one language. This is the first, the most elementary thing about thinking with ideas.
When you think with experience, you go much deeper and you can express the same experience with many kinds of ideas. Then thought can take this form or that form in any language and through all of them the essential realisation will remain unchanged.
To be convincing when you speak, think not in ideas but in experiences.1
