That’s not an escuse lol? Lots of people figure it out properly. By 18 you should know what you have interests in and what you want to do. If you are that misguided you can delay further education until you have figured it out. Or not at all. Being after high school means you need to know what to do with your life. School is an option.
If you haven’t, you’re just stupid and/or lazy. That’s your prerogative to be that way. But don’t drag everyone else down. And this is also why Americans are increasingly laughed at in the world as uneducated and over entitled. Just because you want to make excuses as to why you can’t learn things, doesn’t mean the rest of the world is following suit.
