What I learned on the first day of PI

1. Finance can be very transient. Stock prices can change almost every minute. $400 billion worth of stock value can be wiped out in a matter of months.

2. Figures are dehumanized. That's why it's so easy for banks to just lay off 52,000 workers. They don't see the people behind these figures.

3. If there's anything that approaches infinity, that would be news.
