I’m getting a dish washer

Ok, really, this is not just about getting a dish washer.

Hey Laura,

I am just writing to let you know that I am going to buy a dish washer when we move to the new place. This is by no means my excuse to slack off. Let me explain to you why.

A dishwasher costs between AU$400-700. Let’s buy one for $500.

I spend 15 to 30 minutes each day, after dinner, to wash the dishes. For the sake of simplicity, let’s say I spend 20 minutes a day on average. That’s about 2 hours and 20 minutes per week, or 121 hours a year.

A dish washer will last for a very long time, but let’s use the 2-year warranty period as a base line (Imagine the machine breaks down after 2 year, we can just throw it away). That will be the equivalent of trading AU$500 of investment for 243 hours of my labour. Basically, the machine will work at an hourly rate of approximately $2/hour!!!

In other words, by not using a dish washer, I am working for $2/hour. If we add water and electricity and washing supply cost, I don’t think my hourly rate can reach $3.5. If you insist on numbers, I can follow up with some maths.

On an economic scale, using a machine clearly wins. Let’s discuss the quality of life aspect.

The only downside I can see is that we may run out of supply every now and then. We can simply bulk buy it, once a year.

Let me know what you think. If you don’t have any valid objection after 2 weeks, the decision to buy a dish washer will be considered final and will be executed upon our move.

PS: By the way, I also propose you buy a slow cooker, a food processor, and a robot vacuum cleaner (and fancy designer perfume).

PPS: I’m pretty sure that our parents had this similar argument when the washing machine was first popularised.

Don’t (just) follow your passion

Nowadays, follow your passion has become a motto. I believe it is overrated. Passion can come and go in the blink of an eye. Because of its intensity, people sometimes mistake it as the substance although it is, in truth, nothing more... Continue →
