Assuming a tank is a niche and a tap an income stream,

A tank with several taps is multiple streams (e.g. 5 taps to 1 tank)

While a multiple hustle is like having several tanks, with each tank having just one tap.

The advantage of having 1 tank with multiple taps is the tank gets filled quicker than when you have to fill multiple tanks.

LET'S GIVE A PRACTICAL EXAMPLE:

In real estate, as a niche,

Property sales commission is 1 income stream

Property rental commission is another

Property supervision/management fees is yet another

If you can monetize your real estate website, YouTube page, Facebook page, Instagram page and TikTok handle,

You earn more income from them

Yet, any investment you make in your real estate career will be beneficial to all the aforementioned income streams because they are all intertwined

The reverse is the case when you sell beverages as one income stream

You are also a building contractor as your second income stream

You are into solar energy as the third

And you repair generator sets as your fourth stream of income

Bros, you wan kill yourself?

No be so O!
