"I think you have some fibbers here. Pretty sure you’re not going to amass $1.6m in 20 years of 401k savings."
Not me... To get to $1.7M, I used only the low cost index funds, contributed to the IRS pre-tax max every year, rebalanced annually on my birthday, and TURNED OFF THE NEWS, leave it alone, and stick to the plan. I've never bought a single stock, I prefer to own nearly all of them, including 30% of my money outside the US.
To get to the contribution level I wanted, I split every raise's take-home number with the 401(k). This easily got be to where I wanted to be, as well as a side benefit of controlling lifestyle creep.
Jim Cramer and many of the other famous money media guru's are hazardous to your wealth. There's a huge difference between investing and trading (speculating).
