Today, it's probably zero.
Just like tomorrow it's probably still going to be zero.
Just like the day after tomorrow.
It's probably still going to be zero in a month or two.
Or in a year.
Or in two years.
But it's almost impossible that it's still going to be zero after that...
So how much time can you afford to invest?
Because that's what it is.
It's an investment.
And not a job that pays at the end of each and every month...
