This quote by Cicero speaks to the concept that as we age, we end up being better and more prudent in our choices. In youth, we are often more rash and spontaneous, making decisions without considering the effects. This is not to say that youth is inherently bad, but rather that it is a time of expedition and learning. As we age, we get experience and understanding that enables us to make more informed choices. We end up being more aware of the potential consequences of our actions and are much better able to weigh the pros and cons of a circumstance. This quote is a reminder that knowledge features age which we must aim to be more sensible in our decisions as we get older.
"Have regular hours for work and play; make each day both useful and pleasant, and prove that you understand the worth of time by employing it well. Then youth will be delightful, old age will bring few regrets, and life will become a beautiful success"
