The saying "Time is Gold." means time is precious, like valuable gold. Because time is fair to everyone. Isn't 24 hours a day, 30 days a month, 365 days a year a common time that everyone is all given the same? It's also more valuable because time is irreversible when it passes. It will also be important to spend time well because the way you speak and act at that time can be a reason for regret. For that reason, it is important to make good use of your time and plan well and enjoy your time. However, I don't want to recommend planning in minutes and seconds to make the best use of your time. This is because you can get tired easily and quickly.
