SPEND YOUR TIME ON THE RIGHT THINGS
Before I started using Haiku Deck, I really spent way too much time on my slides--and honestly, even though I was trying, they didn't look that great. I would spend literally hours fussing with things like which font, and spacing, and having my bullets reveal one by one, and really, that was the wrong thing to spend time on.
Now I like to spend my time searching for just the right metaphor, and just the right image to illustrate it. To me it's worth the effort--and overall, it still takes less time.
(As for the homemade Bolognese? Well, that's just one more thing that I think is really worth the time.)
