Seeing what stocks other people are buying completely humbled me about my own portfolio

So I've been investing for years and honestly I thought I was doing pretty well, nothing crazy but decent returns, portfolio is growing, and I felt good about my strategy and everything. Then I started looking at what other people actually hold on blossom and man that was humbling as hell, like I'm sitting here proud of my 40% voo 30% individual stocks 30% cash thinking I'm being smart and diversified, meanwhile everyone else my age is way more aggressive and honestly crushing it because of it.

For instance I saw one dude's portfolio that's like 80% growth stocks and he's up 45% this year while I'm at maybe 18%, which made me realize I'm probably being too conservative for someone with 35 years till retirement, but the weirdest part was seeing how many people just hold 3-5 positions total and do better than my diversified 25 stock portfolio, kinda makes you question if diversification is actually helping or just watering down returns tbh.

Not saying I'm gonna copy what other people do but it def made me rethink my whole approach, like maybe I should take more risk while I'm young instead of investing like I'm already 50, idk… anyone else compares their portfolio to others and realizes you're way more conservative than you thought? Kinda a weird feeling…
