I love it when everything works just right. The heating system keeps my house warm during winter and doesn't put a hole in my pocket, the car still runs perfectly even when left outside under a few feet of snow, the lights turn on when needed, and my computer sends me reminders of any other things that need my immediate attention.
Being efficient saves money, and with technology today, there is no other option than to embrace efficiency. If you don't embrace efficiency, your antiquated systems will just wipe out your bank account in the long run.
