What’s your mindset when you got a great return on a stock, but another stock has an even bigger return?

I own ROKU which is a meaningful part of my portfolio and I should be happy up +120%.

But I'm sulking because instead of ROKU, I could have invested in META and be up 168%, Nvidia up 246%, Tesla up 116%, Draftkings up 238%, Affirm up 170%, Carvana up 599%.

Instead of being happy & focused on my portfolio, I'm focused on the additional money I left on the table. Curious how others in a similar situation approach this?
