I believe the answer is:

air

I'm a little stuck... Click here to teach me more about this clue!

'we all' is the definition.
I can't tell whether this definition defines the answer.

'an excellent right to it' is the wordplay.
'an excellent' becomes 'ai' (resembles 'A1', old-fashioned term for excellent).
'right' becomes 'r' (abbreviation).
'to it' says to put letters next to each other.
'ai'+'r'='AIR'

'have' acts as a link.

Can you help me to learn more?

(Other definitions for air that I've seen before include "Divulge" , "Ventilate, say grievance" , "Atmosphere, manner" , "Of which 78% is nitrogen" , "Bearing, manner" .)
