I only witness it whenever any of my work colleagues anyone with a phone wants to show me a video. Always have to sit through ads before & during the video. Absolutely horrific. Mind you they also have to close multiple pop up ads in every app they ever use on their phone. I couldn’t live with it & not learn how to deal with it
A close friend sells a product on eBay. A product most households have & my friend collects when it’s no longer wanted which is cleaned, sorted & resold. Has now left 9-5 job to run it as a business.
This friend is exceptional at exploiting niches & will likely become amongst leading sellers of this type (is well on the way already having done it before with a particular collectible). Interestingly, reading through the suggestions here, previously collected & sold scrap before pivoting.
I’m very proud of them!
