I don't know anything about the person in question, but any "profit" number is going to have to be fictitious anyway. Ideally, you make as little profit as possible so that you avoid paying taxes. You want your money working for you rather than going to the government (or sitting in a bank account). This is one of the nice aspects of taxes and tax avoidance -- it provides incentives for companies to continue investing. Anyway, the point is the person could give an impressive sounding number (indicating that they are bad at managing money) or they could give a tiny (or even negative) number. It's kind of lose-lose.
But I agree with you -- anybody posting "I'm making $X/month doing something that seems easy" is usually trying to sell you a book/workshop/seminar (which is where they make their real money).
I agree and observe the same. I honesty do it because I want to show you can build a business without venture capital funding, and do it as an indie (and in my case solo) maker with a strong disregard for hip tech stacks and frameworks.
I sell a book but that’s less than 5% of my income. 95% is business.
In terms of money, if you just save enough and have low costs, it means potential financial independence.
I think the most joy I get is from making, so I will continue that. Money was the goal in terms of me having to pay my bills, but the second goal was always that I just like to make things.
Before websites, I made music and visual graphic art. Making makes me happy.
