Ask HN: Do you have a side hustle?

I like hustle culture. Working a 9-5 where I use my disposable income to invest in different side projects. They make a profit, mostly through AD revenue and affiliate commissions. I also run a small consultancy helping companies secure their IP and business secrets. Thinking of going all in on that and turning it into a fully fledged company. What side hustles do you have? Interested to hear other ways people are earning money on the side apart from their main gig.
