You have raised very important points in your message, but you have not detailed them well. I would like to add regarding security that it is crucial to remain vigilant against new threats such as scams and data breaches.
I would also like to add that it would be better to develop an asset allocation strategy that includes cash and other less volatile investments to better manage market fluctuations. I find this better than the idea of an emergency fund.
I would also like to add that the notion of long-term investing should be a bit nuanced, as the market evolves rapidly. Sometimes, it is better to be flexible and know when to take profits.😅
