This quote by Plautus speaks to the concept that knowledge is not something that is gained simply by living longer, however rather something that is gotten through using one's own abilities. It recommends that knowledge is not something that is merely handed to us as we age, however something that we need to actively look for and cultivate. It indicates that wisdom is not something that is necessarily tied to age, but rather something that is made through making use of our own abilities and knowledge. This quote encourages us to use our own abilities to gain wisdom, instead of counting on the passage of time to do so. It suggests that knowledge is something that is made, not something that is simply provided to us. It is a reminder that knowledge is something that we must actively pursue, and that it is not something that is just handed to us as we age.
"Raising children is an incredibly hard and risky business in which no cumulative wisdom is gained: each generation repeats the mistakes the previous one made"
"The man who makes everything that leads to happiness depends upon himself, and not upon other men, has adopted the very best plan for living happily. This is the man of moderation, the man of manly character and of wisdom"
