This quote suggests that the person isn't devoid of emotions but chooses to be less emotional in certain situations. It's like having a heart but deciding to show fewer feelings in specific circumstances.
Sometimes, people need to protect themselves or make rational decisions, and being overly emotional can cloud judgment. So, they use their heart less, meaning they keep their emotions in check, to think clearly and act wisely.
It's important to remember that showing less emotion doesn't mean lacking empathy or compassion. It's a choice to maintain control and make decisions based on reason when needed. So, this quote reminds us that emotions are powerful, but knowing when to use them less can be a strength in navigating life's challenges.
