Your approach to stock management is interesting, especially your focus on long-term growth. However, remember that diversification is key. Investing in Visa, Mastercard, Gold, Berkshire Hathaway, Lenovo, and Getinge is a start, but consider exploring different sectors and asset classes to mitigate risk. Also, keep an eye on global trends and adapt your strategy as needed. As you mentioned, you believe these companies will "handle the current Corona crash" - resilience is important, but so is adaptability!
