WHERE were you when I was an idiot in my 20s and half of my 30s trying to strike it rich with that 10,000 percent gain stock?
You gave the ONLY advice an investor needs.
We've probably all been there. I remember a few decades back trying to play China and India and did real well for a while until it came crashing down. And then I bailed out during one of those early 2000s crashes and bought back in at a higher price.
I eventually learned those "Coffee House" investor strategies are right. It is counter-intuitive but lazy investing works well. Also - increase your savings percentage every time you get a raise. That was the game changer for me that allowed me to comfortably retire.
