Ask HN: Successful one-person online businesses?

Not sure if this counts. I have created a simple landing page open source project: http://rails-landing-page.herokuapp.com/

I get a lot of consulting (development + design) business when clients learn about us via this application.

I also use it set up landing pages for any Startups/SMEs are developing their MVP/Beta application with me.

My sales are $2000/day, 7 days - I'm in my 15th year of business. 100% of my presence is automated (I do nothing day-to-day). The only advice I'm qualified to give, is how to succeed: don't listen to anyone elses advice: use your brain. It is 100% common sense - everyone elses opinions are uninformed and almost always from someone who doesn't really know. Nobody who has succeeded will willingly reveal how to succeed - they're too busy enjoying the fruits of success to waste the time. If you find someone who is willing to tell you, they are usually fake - the "telling you" part is a cog in whatever scam they're involved with (stock investment, bitcoins, realestate, whatever).

Read my lips:

COMMON SENSE.

And, no, I like my income. I'm not telling what I'm doing!
