The poor eternus is an over focus on the present, and you don't worry about planning or how things went into the past. This is a better balance than to be so well balanced that you're in neither fully. And that's what Seneca's book is so good about, actually. The difference is, when you're doing that kind of behavior, you're not really ever stopping to enjoy anything or save or anything, or just be. It's always planned on the next thing.
