“Talent develops in tranquillity, character in the full current of human life.”

Yeah, kinda

Rings true for me!  There's what I think I am, but once in the world with other people, expressions of myself arise that I never knew were within me.  All of life is a dialogue — my words and actions precipitate a response.  If I do not pay attention to the response, it is but a one-way road, likely to a lonely end.  Learning from the world's response to my actions builds character — what kind of character is still up to me.
