I'm a time served joiner with a local builder who liked things doing right... do your best all the time is what he taught me!... and a good job is a tidy job! Another good habit I picked up is how important it is to always respect peoples houses.
So after 28 years of fitting windows, I'm sure I know all the important things that customers require. I still enjoy transforming peoples houses, one of the most rewarding and satisfying parts of the job is seeing customers smiling faces when they see their new windows, doors or conservatory completed.
