Is anyone rich here?

I'm far from rich, but I'm not dumb either. Based on a $12k initial investment and $1k additional per month, you'll have about $316k in 11 years based on a somewhat optimistic 12% average annual return. Is that going to be enough to retire off of? Only you can answer that question.

My only advice would be to pay attention to the expense ratios and fees of whatever mutual fund or ETF you choose to invest in. Some of them are pretty high and will cut significantly into your bottom line.
