How to prioritise when working on multiple high-visibility projects with limited time

Hi everyone,
As we plan for H2, multiple high-visibility projects have been assigned to our team. Due to limited resources, we’ve been split into virtual groups, and I'm expected to contribute to multiple projects simultaneously.

The main challenge is prioritisation. When I ask my manager, the response is usually “everything is important,” which makes it hard to focus. I want to avoid a situation where I’m spread too thin and end up underdelivering.

Would love your thoughts on:\

1. How do you prioritize when everything feels urgent?\
2. How do you manage bandwidth while still setting realistic expectations?\
3. Any frameworks or tactics that have worked well for you in similar situations?
   
   Thank you
