You have that big presentation coming up and you cannot get yourself to get started on it. Too many distractions, and too few ideas what to actually do.
Some ideas:
Open a little (paper or digital) scratch pad somewhere and start jotting down ideas weeks before your presentation. Presentation design and storytelling are creative processes that need some brain incubation time. Your subconscious mind will chew on ideas you started without you realizing it. It is possible to crank out slides the night before the presentation, it is not possible to crank out creative ideas under last minute time pressure. Start early, even with scribbles and notes
If you have a bit of time, postpone looking at existing decks and start fresh. Maybe the thought of having to iterate that same old boring, stale presentation is preventing you from getting into it.
The other extreme: make one really great “killer” slide for which you have a clear idea and push it all the way to the finished product. Ignore story flow and its overall context, just make it. This ice breaker or sneak peek of what slides in your deck could look like might get you over that initial writers block and get motivated to get started.
