If it takes you 50 years to turn $1 into $2, then you have not won. Put your money in a bank account instead. If you can do it in a year, you've won. But if you start with $1 then after one year you have $2, then the next year you have $4, etc. It takes less time if you take a $1000 loan and turn that into $2000. Of course turning $1000 into $2000 is harder than $1 into $2, so take a loan as big as you can still double ;)
