A vademecum? A to do list? A series of recommendations? Something like the infamous "10 top things to do in Florence" that you can find in many websites? All of the above, but not only and not mainly. Formally, the book consists of a list of 20 suggestions (or paternal exhortations, if you will) for the 14 weeks of a regular academic semester. Twenty reflections (the book has been written during the 2020 lockdown in Firenze) that I have drawn from 20 years of teaching architecture students abroad. Is this book addressed to students only? If students are those who pay tuition fees to a school, then these pages are not addressed to them only. But if students are all those people who are curious and still able to learn something from anything (either through an officially organised program or on their own), then this book is indeed for students.
