"Time flies on wings of lightning, we cannot call it back." I've written on this subject a few times and it's still something I greatly struggle with -- and I lived two years on a rigid schedule, absent TV, email, friends, dating etc., waking up early and going to bed by 10:30.
As I imagine some of you might also be having similar struggles with prioritizing your time, I'm confident you'll enjoy this brief video, incorporating words from Elder David A. Bednar, as well as the full video of Elder Ian S. Ardern's recent general conference talk, A Time to Prepare.
