I've worked as a labourer driven taxis and school buses and been a car mechanic - whatever I could do just to get by. But it does mean that I know a little bit about a lot of things.
At a car dealership the person who sells the car is the hero and also gets the commission. But if the mechanics don't service that car well the customer won't return.
I wanted to be a mechanic. When I was 14 I wanted to quit school and go work on my car. But my dad said Son you shouldn't do that. You should stay in school until your education is finished and when you're done don't make your hobby your job.
If you examine this I think that you will find that it's the mechanics of Japanese architecture that have been thought of as the direct influence upon our architecture.
The sanitary and mechanical age we are now entering makes up for the mercy it grants to our sense of smell by the ferocity with which it assails our sense of hearing.
