Is it a slap in the face?

Options strategy: protect the underlying stocks
Suppose I went long on a stock and bought its shares, thinking I'd be a shareholder. ^^ BUT at the moment, the stock starts to fall, shall I hold it? Sell it? Or buy the dip and add my position?
Whoever investing in stocks has experienced that. We all dreamed of becoming rich. But the wobble has caught us by surprise.
What to do? Do nothing and let it fall?
- If I sold it, the floating loss would be realized...

Last year, during the COVID-19 pandemic, the stock market was halted twice, followed by a strong rebound that created a wave of so-called stock gods. Riding the wave of q&m dental's stock trading fever, I entered the investment market and experienced the phenomenon of 'buy whatever rises.' Later, during a market downturn that seemed inexplicable, I realized that as the hype faded, it was revealed who was swimming naked. This helped me understand that investment is long-term, and short-term fluctuations really do not signify much. Whether it's cutting losses or missing opportunities, these are all necessary experiences. One must not dwell too much on short-term gains or losses. What's important is decisiveness and unwavering conviction.
