This hourglass sand timer reminds us to carve out 15 minutes a day for what truly counts. It demarcates a very modest and manageable period to dedicate to the important things we so often let slide - finally writing that letter to an old friend, rationally analysing our career ambitions, or playing in a concentrated way with a child. It’s an antidote to wasted days and a counter to the urge to procrastinate, prompting us to do a minimum of what really counts.
