My money has been in a combination of Google and Amazon since 2004
Since 2009 GOOG has looked like a ruler straight line on an exponential scale = 21%/ year
Since 2009 AMZN has looked like a ruler straight line on an exponential scale = 38%/ year
That is 12 year of fat, could be followed by 12 years of lean.
I was a child stock owner in the 1967 - 1982 flat spot. That was a 15 year flat spot.
I was a stockholder in the 1987 crash. I did not sell, and it was back to normal in a year.
