What does this quote mean?

[meisje]

The physician can bury his mistakes, but the architect can only advise his client to plant vines - so they should go as far as possible from home to build thier first buildings.
-Frank Lloyd Wright

1. That the mistakes architects make are very obvious,

so they should do their first works where their likely customers will be less likely to see them.

2. Pretty straight forward

A doctor's mistakes would end up with a toe tag, and most times the deaths won't be questioned.

Architects should build their first houses so close to home that the owners would come back on their asses with a vengeance
