"Academically, if you can't measure something, you cannot quantify what it does" - Carmine Gallo
How do you measure passion ? You know when it's there and you know when it's not, but what metrics can you use to say that someone has more passion than someone else ? Passion plays a huge role in success, but it can't be measured.
Measuring and understanding are two completely different things: Measuring is about compliance, whereas understanding is about empathy.
