Growing up we always learn about time management however as entrepreneurs sometimes it's more about energy management since no two days are the same.
For me, and many of my friends there are busy months in business and slow months. I would normally panic a lot in the slower days but recently I've decided to take this time to build, branch out and focus on my business because when the season picks up I'm surrounded by client work. I also take this time to recharge on a personal level. Hitting up an extra yoga class or taking longer meditations in the morning (sometimes even a mini vacay). This way I'm recharged and ready to run in full force come busy season!
