I remember playing (my) football (your soccer) in school and my neighbourhood as a kid.
If you were going to strike you needed to be pretty sure that you can score or that you can take the heat from your team mates if you fail.
In contrast watching kids play sports in the US, everyone is constantly trying to lift each other up after failure.
These small cultural differences easily add up in how you carry yourself in business.
Negativity seems to be culturally frowned upon in the US (what a downer). Positivity seems to be culturity frowned in Europe (naive 'happy go lucky' kind of guy).
