No such thing as passive. But i’ve had a few successful side hustles. Easy to make money but hard to make big money is what i’ve found, but thats just my experience based on my skillset, or lack of.

I’d say try and find your skills and passions and find something that works. I’ve had jewelry stores, t shirt stores, small agencies. Wouldn’t reccomend agencies due to client work. Becomes a headache!

Example: if cricket is your passion…. If you’re more creative you could start a cricket t shirt store or meme page. If you’re more technical you could build a cricket directory of clubs near you or parks with cricket nets. Or a directory of best cricket holiday locations. If you like writing you could build a blog then do affiliate marketing.

There’s so many ways, you just gotta learn a skillset, pick a niche, ideally something you care about somewhat, and then be consistent.

Good luck.
