In my experience, we need to pay careful attention to the words that people use to describe themselves.

It's other people - not you - who can refer to you as being classy. Referring to yourself as being classy is not classy.

It's other people - not you - who can refer to you as being trustworthy. Referring to yourself as being trustworthy raises red flags for me.

Same goes with high value. The best way to show yourself as having high value is to treat other people as having high value.
