"Eat what you want to eat and meet who you want to see" means: you can do whatever you want, and you are free from any constraints.
This sentence reminds me of my colleague:
He is an easy-going person. Besides work, we also talk about some topics in life, such as parents, children, wives and so on. Actually, it's just a chat The biggest feeling of chatting with him is that there is not much psychological burden, which is how I feel.
I remember one time, when he talked about traveling, because his wife didn't agree, but he had made a small plan and didn't want to ruin this feeling, so he was going to go step by step without her consent. Then, I asked him, "Don't you fear that your wife will be angry?" My colleague said, "Eat what you want, meet who you want and do what you want."
Yes, for casual people, let's live a more chic life. But I personally feel that no matter what you do, you must care about your family's feelings. After all, life will continue.
