It’s not how many years you’ve lived in your life, but how much life you’ve lived in your years.
In the end, it’s not the years in your life that count. It’s the life in your years. (Abraham Lincoln)
It’s better to find the source of a problem and being unable to fix it than it is to fix the problem without knowing its source.
It is better to debate a question without settling it than to settling a question without debating it. (Joseph Joubert)
