By having your weekly review at the start of the week, you’re refreshed from the weekend and can focus on figuring out what the coming week’s big tasks are. For example, you could look over your schedule to see if you have any important meetings or projects you need to prepare materials for, then block off prep time off on your calendar early in the week, before everyone’s booked you with meetings. Make sure you check your schedule through the next week’s Monday so you’re not stuck scrambling to prepare something the day of.
