"Life isn't short--it's LONG, and you have a brief moment in that life to maximize your preparation for the rest of it. Use it wisely."

Anyone can die any time if they're unlucky enough. Leaving much of the fun until you're old may thus be a very bad strategy.

I agree one should focus on productive activities already in their 20's, but meaningful leisure is important too. It's meaningless leisure that you do only out of boredom that people should restrict more - for me that would be social media, news and gaming.
