I like people who are enterprising, who have the courage to change, and who are not afraid of being wrong.
(Si può anche tradurre quello come: "... who are not afraid of making mistakes".)
I like people who get involved[1], who always want to improve themselves, to know[2] and to discover new things.
[1] Letteralmente, "si mettono in gioco" = "Put themselves in the game". È un frase idiomatica in inglese, ma "get involved" è più chiaro. [2] In questo contesto, forse "conoscere" anche = "to understand".
L'ultima frase non traduce parola per parola, ma l'equivalente inglese è:
Those people have precise objectives, and they are focused on them until they achieve them.
