How To Double Your $100 Investment
To double $100, find something worth $200, buy it for $100, and sell it to others. You may need to negotiate with the seller to sell you the product at $100. You can visit eBay, Amazon, or Craiglist to find any product. Many products exist below their perceived value on these platforms.
Another option is to invest $100 in sales and marketing skills. That's an investment in yourself to earn more than $100.
Don't confuse doubling $100 with a million dollars, and don’t confuse doubling a million dollars with a billion dollars, as the scales differ. Doubling $100 requires different skills than doubling $1 million and different skills than a billion dollars.
However, acquiring the right skills along the way is important. Learn to sell and market at $100, learn to scale at $1 million, and learn to manage at a billion.
Opportunities to double your money get less the larger you get.
But keep learning!
