No one will argue with the fact that time is the greatest value. Time cannot be replaced by anything; lost time cannot be returned. The saddest thing is that it is impossible to correct your mistakes or actions committed in the past. We can only learn from our experience so that we don't make mistakes in the future. But even this is not always possible and not everyone succeeds in doing it. Alas, a person begins to truly appreciate the time allotted to him by fate only with age. Young people feel like they have an eternity ahead of them.
I agree with you, that's the mistake many young people make they don't value the time they have. They tend to dwell on useless things like chatting with friends for hours and socializing without a clear goal and not getting any results, many of them get stuck for long periods without thinking about their future.
They only realize this when they see their friends starting to plan their futures and achieve their goals. Perhaps only then do they realize that the time they've wasted can't be recovered. This realization can be a valuable lesson, but it's often accompanied by deep regret.
