Ever met famous people (founders, influencers); how are they different IRL?

Guess the question is too broad. I'll share my experience so it's probably easier to understand. So I met the founder of a consumer brand. Decently famous on social media, does very funny, witty jokes. You make this image of them "cool, yo vibe" in your brain before meeting them. But this person is the calmest, most patient, overtly respectful guy. How in Hindi we use "Tu," "tum," and "aap" for ascending levels of respect, this person talks in "aap" even in English. He is also that funny, witty person, but in a funny way, and not offensive. It's nice that fame hasn't got to their head. I am genuinely surprised when I meet good people in this bad world. The paranoia you grow up with in NCR makes you doubt every other person.

I once entered the Mumbai airport washroom along with Dev Patel How are people different IRL? When someone is peeing next to you, you kinda stop putting them on a pedestal and being awed by them 😂

I have met founders/tech influencers who are somewhat famous in the tech circle they belong to; not to the overall tech circle or common people may not know them. But most of them have been very humble and down to earth (exceptions are everywhere).

Sharing on Vijay Shekhar Sharma: Most energetic person I have ever met. Very nice in real life. Does not appear to see people as above or below him, talks to everyone with full attention Honestly a refreshing human in every way

Had a chance to meet founders of one the biggest fintech company based out of bangalore. Very nice and calm vibes. Patiently asked questions on few things they were curious about. Offered some food/ coffee. Genuinely impressed with what they've built!

I have worked with a Co-Founder of an Unicorn.. Feels like friend, I was shocked how normal they live - and the next day I was reading their interviews & photos in newspaper... and then watching them infront of me.. huhh, it was a very weird feel.

I met Shankar Mahadevan (Breathless fame) in a small private gathering. After few handshakes & pleasantries, everyone requested him to sing a song. I always had this thesis (true as well, remember Atif Aslam) that with growth in sound technology, singers might sound different in real. This guy was totally different! Depth & clarity in his singing voice was amazing. He sang “Pretty woman” KHNH, without any instruments & mic. I was highly highly impressed by his voice & skills.

Can someone with social media/content creation knowledge tell how to people actually become content creators? And I mean starting from scratch. You cannot just start making content and think that your channel is going to grow on its own. You will need help. How to contact agencies who might want to work with you? Do you reach out to them or do they reach out to you? Also how would I know which is a good agency and which one is useless?
