Recently, I got really excited by an idea and working on it. Its something that I find very interesting and I personally feel I could learn a lot and the final product would help a lot of people.
But I am not sure (provided the product is really good and helps a lot of people) it will be a big business. My best case scenario is a small section of my target customers would end up paying for it. But I am not sure if the eventual revenues will be in the millions.
I also saw a YouTube video where Sam Altman where he says the big startups are made in small but rapidly expanding market and such startups (with great execution) will evolve into the billion dollar companies. I thought his advice was basically to focus on "big" things (I may have misinterpreted this but this is the sense I got).
My gut says to work on the thing I am excited about and even if it doesnt reach a huge user base, make sure whatever customers I get is very excited by it.
My personal ambition is to build a product that people love and which gives me a decent revenue to hire a few people and to continue working on it.
Thanks for reading and sorry for the long winded post.
You can't know whether your company will be a billion dollar one ahead of time, unless you're really working in a large problem space, such as biotech, space exploration, etc, but it doesn't look like you are. Therefore, just solve the problems you have, make money (preferably without raising venture capital), then use that money to fund your business and hire employees.

From your last sentence, it seems to me that you already have made a decision in your head. You are leaning towards building a sustainable bootstrapped business.
I guess focus on building the product, providing value, start selling your product early on and let the market define whether its a billion-dollar company or not.
