Quality.

Thanks to large corporations the word Quality has changed from Craftsmanship and Pride to the Lowest Standard a customer will accept.
It used to be, "buy cheap, buy twice". 
It used to be, buy expensive quality to guarantee long lasting product. Now it is, buy expensive, return to manufacturer for fix, argue with manufacturer over warranty, stop using product, let it rot in your garage while you keep using the cheap product you bought for few days emergency use.
Now it is "buy cheap, buy the insurance, get it replaced if fails".

Start of stupidity.

Here, hold my beer and watch this.

Teacher

As a self-taught mechanic I can only conclude that my teacher was an idiot.

Tragedy

A tragedy is an epic story you don't live to tell.

Wars

I am fed up with rich old politicians dreaming up new wars for young people to die in. The job of a politician is to prevent a war. If you are a politician do your bloody job and save lives.

Stop waste and clean up the environment.

Use this old saying.
"Use it up and wear it out. Make it do or do without."

Dogsheep.

Just once I'd like to see a sheep herd dogs.
