Do you let any maintenance items go longer than recommended?

I pretty much do everything on schedule. Perform all my own maintenance and enjoy doing it. Fluids like brake and coolant get changed every 5 years, engine oil annually, transmission and rear end on mileage. Belts and hoses as needed. I stay on schedule and have had good results doing so. Been doing this with all our vehicles, boats and motorcycles. Haven't had a engine, transmission or axle failure yet so it must work.
