To address a variety of important deadlines, invest time blocking off time on your calendar for them. Define what you want to get accomplished during those focused times and hold yourself accountable to completing the activities. Then, add in "flex" times on your calendar. Periods where you do not plan anything formal, but you have blocked off time to work on the important projects should the original time you allocated not be enough.

Stay organized by identifying a timeline which prioritizes critical tasks while still accomplishing all of the deadlines. Then if after planning this out there's still a need for concern of realistically being overwhelmed due to a lack of resources or time constraint. Then communicate this situation to the project manager and determine if the timeline can be extended or if the requirements of the work can be reduced or at least be satisfied with a status update of the progress or request if overtime is an option or hiring additional help to meet the high level of demand that can't be accomplished by the current production ability of the current team.

Start by drafting an outline that covers all the key tasks, then refine it to meet client expectations. Stay flexible to accommodate any last-minute changes, and delegate tasks where possible to free up time for critical work. This approach should keep everything on track and allow for adjustments if needed.
