Answer:
I am not as well worded as the other guy, but my opinion on what it means to love is that your brain would power down and suddenly your heart powers your body. When you have the feelings of love for someone, you will randomly do something for them that you would do for no other. For example, my little brother asks me for everything, and since I have love for him I will get him those things. Even if I think he can do it himself. Love is also like that ride or die feeling. you would do anything(mostly) for the people you have this connection with.
Step-by-step explanation:
If your asking about what the person means in the quote.
He means I can be very smart (highest GPA). I could be so smart that people come from all over the world to asks ne their questions. I am indeed famous to most. But though I have fame, fortune, and wisdom I still have an empty heart. Every day I come home to an epmty house, after seeing all those people connecting with their families, showing real love. I had left my family just so I could have this fame. This fame for my mind. I had left behind so much in order to be lonely. And although I see thousands of faces every day, they are not the faces of loved ones. And sadly without them, I would have never made it here.
The End,
Sorry if this didn't help much.
