How could you not want to be super productive and successful?

I don't understand how anyone can be happy with being mediocre. We only live once, why waste it on being average. I'm not saying being an entrepreneur, or billionaire or anything like that or it has to be a big business, but just trying to be the best version of yourself. I don't understand how people are ok with just being average.<br><br>Edit: I'm not saying I'm super productive far from it, but I just don't get it.
