I am a very hard worker and am willing to do whatever it takes to make a substantial income but my questions for you is how could I do this at college? How could I generate enough income from multiple sources of flow that will keep me afloat for years to come? I am in desperate need for help. Thank you very much, I would be in great appreciation if I could get a response.
The gems and jewellery industry has been economically active in India for several thousand years.[187] Until the 18th century, India was the only major reliable source of diamonds.[183] Now, South Africa and Australia are the major sources of diamonds and precious metals, but along with Antwerp, New York, and Ramat Gan, Indian cities such as Surat and Mumbai are the hubs of world's jewellery polishing, cutting, precision finishing, supply and trade. Unlike other centres, the gems and jewellery industry in India is primarily artisan-driven; the sector is manual, highly fragmented, and almost entirely served by family-owned operations.

For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
