It's my pleasure! I love talking about stuff like this!
Hmmm...Maybe look up something like schools of philosophy, then pick random ones and look them up, watch YouTube videos, etc. Then when something resonates, you'll know. Maybe you'll find more than one, and they could be totally unrelated, or only seem to be.
Within different schools of philosophy, you'll find different philosophers. In Stoicism, there are several, and I definitely have my favorites and my least favorites. I'm drawn to the extroverts and the leaders, like Marcus Aurelius and Seneca, and at the other end is the cranky introvert Epictetus, who was a former slave and is kind of harsh, but still said some really good shit. I wouldn't hang out with him, though. Seneca gets on my nerves, too, probably because our personalities have some similarities, but his writing was brilliant when it wasn't overbearing (this is the first time I've come to realize why he bugs me, it's pretty funny). I love Marcus Aurelius because he was so focused on justice, and because he had all that power as a Roman emperor, yet constantly strove to keep his ego in check and to be in service as a leader, which is my ideal for the world, and I'm so sad that I don't see any living examples who are consistent like he was and truly dedicated to such things. Power corrupts, and he fought that. I genuinely admire him, and that's rare for me.
Anyhow, those are my suggestions, maybe they'll help, maybe not.
Oh yeah, you could also start a thread like, "What's your favorite philosophy/philosphers and why?" Something may come up to pique your interest I've seen nihilism mentioned many times, and of course efilism, anti-natalism, pessimism, and Schopenhauer.
