I think that I would like to have enough passive income to provide me with about $30,000 a year. So I would probably need investments or interest bearing savings of about $900,000 - $1.2 Million. I would also need to own my own house and have no debt. I'm guessing that this will take me about 20 years to accumulate that much more wealth if I play my cards right. So I have a goal of having the option of living off my passive income by the time I am 45.
Of course, just because I could stop working doesn't mean I would. Who would want to give up writing?
So, I ask you, what is your magic number? How much wealth do you want to accumulate before you are willing to stop working?
