Risk assessment sounds corporate, but stripped down it is three questions you can ask about anything: what could go wrong, how bad would it be, and what can I cheaply do about it. Applied to daily life, it takes seconds and prevents most common accidents without making you paranoid.
Crossing a road in a new country, ask which direction traffic actually comes from. Renting a flat, ask about smoke alarms and window locks. Riding a scooter, ask what happens in rain without a helmet. The trick is matching effort to stakes; spend your attention on things that are both likely and serious, like traffic, and stop worrying about vivid but rare risks.
The habit matters extra when you move abroad, because your intuition was trained elsewhere. What felt safe at home may not be, and things that look alarming may be fine. For the first few months, consciously run the three questions on anything new, and soon it becomes automatic again.
