Sorry, did I say changes? I meant to say, “throwing the previous version away and building a new one”.
After having presentation ready for weeks, suddenly you realise that it can be so much better. And all the pieces of a puzzle fall in their places. And then it’s just one looooong night and a sleeeeeepy day, and you end up with a perfect slide deck.
Don’t be afraid to throw away stuff that no longer fits. And it’s not about presentations.
