The reason our ideas seem more profound to us than to others is that we understand them better.
And we understand our own ideas better because they have all been formed on the basis of our sum total experiences, perceptions, and opinions — a collection which is truly unique per the individual mind.
Reminder: a little patience in communication goes a long way. Give the other party a chance to articulate their message as they see fit (within reason, of course).
You’ll both do better for it.
