Eat To Eat

I love to eat a lot........... Eat to live or live to eat? I didn't understand its meaning. But one thing I know "we earn to eat". My grandfather told me that dressing is more important than eating because people won't see what you eat but what you wear. So dress up well and stay hungry. But I totally disagree with this. I asked him,"can you stay hungry for five days wearing a suit?" He was speechless. I was the only person who questioned my grandfather in my family. That day I was very happy and ate a lot and slept well to wake up to eat a lot next day again.......................
