'strive to be' is the definition.
I can't judge whether this defines the answer.

'one friend possessing charisma' is the wordplay.
'one' becomes 'i' (Roman numeral).
'friend' becomes 'mate' (mate is a kind of friend).
'possessing' means one lot of letters goes inside another.
'charisma' becomes 'it' ('it' can mean a special quality or charisma).
'mate' placed around 'it' is 'mitate'.
'i'+'mitate'='IMITATE'

'like' acts as a link.
