Get rid of that fancy coffee table you never use, and replace it with a cardboard box.
Remove all unnecessary apps from your phone, but keep the ones that play 8-bit video game music.
Spend an entire week eating only plain toast, and see if you can tell the difference.
Use an old cardboard tube from a paper towel roll as a makeshift microphone stand, and sing your feelings to the world.
