Berk Kaplan discusses several ways to decrease Cycles rendering times. Some, like using a GPU and plugging in your laptop to AC mains. I found others insightful, such as decreasing render performance with multiple GPUs on light scenes. This video might be worth the 10 minutes to watch if you use Cycles.
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
