Save time. If you know the value of time you can create extra time by not wasting it. By not throwing it away in trivial, wasteful thoughts that distract and divert us. By not squandering it in careless words that cause sorrow and eventually return to cause regret and demand recompense. Save time now. For if not now, then never.

if you don't invest your time into your children,
well who do you invest it in?
