Scrum is built on the weekly/bi-weekly cycle. It provides a structure, a routine. It minimises surprises. You know that the planning session is on a Friday, for the work that starts on Monday, so you can get things on order on Wednesday.
It lets you see what’s coming.
It’s not about process, it’s about expectation. The more you can plan, the less you have to think about. You know when it’s coming and you can line things up in advance.
Have a heartbeat. Know what happens on a Monday, even if you don’t know yet what you’ll achieve.
