LOL-- or taken the advice of an even sharper financial adviser and bought Apple ten years ago and locked in a 5,813% return plus dividends!...
...Back then, stocks were - to me - an obviously shitty investment for the next decade...
--and that's because investing in 'stocks' is like investing in 'precious metals'. Can't happen.
All that's possible is to either buy a metal like gold from a dealer or buy a stock like Apple from a broker. Sounds like you settled for a mere 525% return when you could have bought Apple for $6.68 per share and sold it for $426.70. A thousand bucks in Apple could have earned you $61,571.85 which means your limited understanding squandered and lost forever a $56,321.85 opportunity.
OK, that's all in the past but today we can review, stare at our miserable stupid blunders, ponder deeply how we could have ever been so pitifully blind, and resolve now and forever that we'll never again call every single stock 'an obviously shitty investment for the next decade'. Or not. Another choice is to understand what we're good at, decide if it's getting us what we want, and then go ahead and enjoy life. Personally I'll go with the second option.
