Tyre pressure.
When driving a vehicle, we usually give attention to the engine, the make, the kind of fuel and whatnot.
One thing that doesn't get that much attention, one thing that seems mundane, but can make everything better is tyre pressure. It makes the driving more comfortable, the engine more efficient, the brakes more effective and it doesn't cost much.
How can we maintain adequate "tyre pressure" in our creative work? What is it that we take for granted that can make everything better?
