With the polar vortex hammering down on a large part of the US, it seems appropriate to serve up a warm bowl of feel-good chicken soup stories. A poem or two, a peek behind the RBI curtain, maybe a board game… and of course a thought or two about investing. It’s the comfort food of podcasts to get us through these chilly days.

It's time for another 5 stock sampler, where David selects a handful of stock picks from his premium services and serves them up for a free tasting. But what is the theme that ties this week's picks together? No spoilers, but longtime listeners might be able to figure it out before the big reveal.

In remembrance of the life of Jack Bogle, we thought it would be appropriate to revisit this show from December of 2016. Bogle was the creator of the Index Fund, the founder of Vanguard, and an all-around stand-up guy who dedicated his life’s work to helping people invest better. You might say that Jack was the ultimate Rule Breaker, and truly a Fool's Fool.

We're not going to let a couple of losers get in the way of winning are we? Of course not! But it is that time of year when we take a look in the mirror and acknowledge our worst mistakes. In the spirit of transparency and good score-keeping, we present David's worst stock picks of the last 3 years, one lesson tagged to each.

Are you a "for" person or an "against" person? Hopefully we all aspire to be the former, but even so, we all need a little rant once in a while. So whether it’s obsessing over errors, giving short shrift to services, or #VanityPlateHate, let's get it all out now and enjoy the rest of the year on a positive note!
