What changed in your investing mindset after your first big drawdown?

I'd like to ask a sincere question. It seems to me that everyone is talking about strategies and allocations, but the first real downturn has a different effect. While it causes panic for some, it requires simplicity and patience for others. I'm curious how your mindset changed after experiencing a significant downturn. Did it affect your risk tolerance, how often you check prices, or how you think about long-term plans? If you have knowledge and experience in this area, please write to me.
