I'm not sure about this one. It doesn't specify what "making the most out of any given moment" entails, but some people could see it as a justification for a toxic productivity mindset. Even if not seen from this lense, I know people who burn out because they pack their 'leisure time' with too many things to do. Ultimately, it is often hard to judge what is and what isn't a waste of time, so telling people to make the most out of any given amount of time is going to lead to peolpe doing more time-wasting activities faster.
