What do you feel are desired presidential qualities?

Without profiling a known president, what qualities do you feel are a must have for a US president?

These qualities may, but not must include level of schooling, political party, physical attributes, mental stability, and more.
Make a list you feel are necessary qualities to effectively perform the office of President of the US.

My stipulations:
Please use no name references.
Any responses using trump, as a name or a verb, or any context will be flagged.

I prefer you make your list before reading any other responses.
