Leaving my home to "make it" in life. Why does no one talk about the guilt

I'm in a particular phase in my life where I'll be soon moving out of my home, most probably abroad. Even if not abroad it'll be far away from home.

Initially I was hesitant to accept it, I don't want to leave my parents. I'm their only son, they always loved me, they are the opposite of typical Indian parents.

My dad said this is normal; and that all children leave at some point to chase success.

I always had a dream of seeing the world- it's beautiful out there. Mountains, beaches rural Japan, Egypt, I wanna go everywhere. It's like "Not all treasure is silver or gold, mate" kind of dream.

What do you guys think.
