Many people are confused regarding the right application of two expressions – aptitude and attitude. Aptitude is the potential of a person to do certain things due to the natural or the inborn ability or accumulated knowledge and experience. Since it has more to do with intelligence, it can be acquired and enhanced through training and experience.
Aptitude is more about management of a problem or a situation. While attitude is the way a person understands, perceives and responds to certain situations. It is more of a behavioural aspect and can be improved gradually via introspection and self-motivation. It cannot be quantified.
Attitude is related to existing abilities and skills with certain perceptions. It is how a person perceives something. Attitude is associated with character or virtues. It means attitude depends upon underlying values.
