Is it a stupid idea to go and live on my own?

My father has told me that he dedicated part of his life by building an upstairs and downstairs house so that we can be comfortable. When I really think about it, I don’t have to pay a rent, and I would just have to contribute towards groceries and stuff. My thing is, I would want to migrate to another country and live there, but a lot of people tell me that I would be putting myself up for a difficult life. What do you think about this?
