Thanks for the thoughtful words, sleep is a good time to heal. However, life is a blessing so you are correct that we should use all our time making progress in life. Time is a priceless treasure. No matter how rich you are, you only have 24 hours in your day. As I monk in my yoga ashram for 10 years, we were trained to sleep 6 hours a day all year through, rising at 4am daily to benefit from the best time of the day for meditation or writing.
Wishing you well and blessings flowing your way from the source.
