How do temperament and character differ?

Temperament is innate behavior potential; character is your ethical and moral foundation. You're born with temperament; you build character through decisions, discipline, and values alignment.

Can a difficult temperament develop good character?

Absolutely. Cholerics (aggressive) can cultivate compassion; melancholics (withdrawn) can develop courage. Character transcends temperament when people consciously choose values and act accordingly.

Is character development the same as changing temperament?

No. Character development means managing temperament wisely, not eliminating it. A choleric doesn't become phlegmatic; they channel their drive toward noble goals and develop empathy around assertiveness.
