Back when I had my first corporate science job at Wardell Armstrong, a geotechnical company in England, a senior engineer had his own way to motivate us then junior folks to overcome problems with the delays caused by sudden archeological discoveries during mining activities. I remember that one day when I was pulling my hair trying to keep my budget and timeline he said: "If you think that's bad, I send you to build a subway in Rome". And this was also the first time I came here - not for the subway, even though I immediately understood why there is not much of a network.
It is always nice to be back to Rome for a visit. After a bit of work and a Webinar (just learned today what that is) in the morning , we strolled a bit around the city centre. I specially like the lively mix of centuries, some of them remains and others in use, as if it would be normal to have a flat or office on a two thousand year old foundation.
