How do you cope with selling a stock right before it rallies another 50% or more?

You never go broke taking profits but I feel like I missed out on a lot more profit if I had just waited one week or a couple of months to sell. Three examples I had were I bought NVDA, PLTR, and ELF this year. I sold all three as soon as I got a 15-25% gain all have gone up another 50% or more.

NVDA is the most painful one since I bought it at $130 in October 2022 then panic a bit and sold when it started tanking in December 2022 at $160. I gave in to social media and Reddit saying it was too expensive and sold. It is now up 142% just 5 months later.
