Yeah good advice. ^^
Personally if i made $2m I'd stick it in a bank and quit working forever....No need to make tens of millions.
I said $50k month because most think $60 day is BIG money on here.
Thx virus!
$2m isn't enough for a comfortable retirement if you're under 40, especially if you keep the money in the bank.
In the UK inflation is currently higher than the bank's best interest rates. I don't know how it is in the US, but I doubt it's much better. You'll maybe get 1-2% above inflation.
So after inflation you'd have $20k to $40k per year before tax. Pretty crap really.
If you decided to dip into it and take $100k/year then you'd run out before you hit 50 depending on your current age. Even at that, $100k/year isn't a lot. $50k/mo is $600k/year, so $2m would be just over 3 years at that level of income.
If you put your $2m to work you could easily make $50k/mo for the rest of your life though.
With $2million in the bank,at a modest 1% interest rate,you could withdraw $5,000 per month for 40 1/2 years before you would run out of money.
How do you work that one out? $5k/mo is $60k/year. $60k of $2mil is 3%
So he'd have $1667/mo.
Inflation in the US averaged 3.16% in 2011 and in the past 12 years it's averaged 2.55%
So if you can average 3% interest on your savings account you'll get a delicious 0.45% income which is $750.15/mo

Oh, and that's BEFORE tax
I just realized you said "before your money runs out", so yeah, that would work, but if he's 30 then he'll run out of money at 70

If he lives till 90 then he's going to be struggling for another 20 years of life after living on $5k/mo for the last 40 years
OP I think your attitude is wrong. Big money is everywhere - also IM, but it takes time.
You say Adsense is not big money? There are people who make $100K+/month with Adsense... And yes, one day they started with $50 bucks/month
There are people making $100k/day with IM never mind per month. The big money is in advertising. I know many who are into advertising in a big way and they consider $3k/day small-time advertising funds.
The creator's of farmville, zynga were investing $1mil/day in facebook advertising at one point. I don't know what they're doing now, but it'll be a lot since they're worth about $7bil.
We can't all go as big as zynga, but even reaching $10k/day on fb ads and making 200% returns you'll be doing $10k/day profit or $3mil/year. That's pretty big money
