do you ever take others' bad choices in life as inspiration to not make those same choices?

When I'm older I'm not going to be lazy and I'm going to do things to enjoy life to the fullest. My parents are lazy and all they do on the weekends is stay home. They never go out even for their own entertainment. My dad says he's 40 years old and that's why he doesn't do much. I only find that as an excuse because my teachers are much older and they still go out and do a lot more things. Even my friends'parents who are relatively the same age still go out to have fun, so why can't my parents do that? When I'm older I won't let age tell me whether or not to have fun outside of home and I'm still going to do physical activities and hang out with others, because this lifestyle of working and staying home and nothing else sounds like a living hell. I hope I don't sound too rude but these are my honest feelings
