On the subject of gambling versus investing, I would like to share my experience as an LDS Card Counter. I play Blackjack in Nevada casinos in a way that gives me about a 1% edge over the house. This is proven by math. But to get there, I had to memorize a set of playing decisions called basic strategy, count the cards as they are dealt, figure out the true count by estimating how many cards remain to be dealt, size my bets accordingly, and memorize when to break from basic strategy according to the true count.
Due to my Autism, I can do all of the above in a busy casino, and I can do it while chatting with the dealer or other players to appear less obvious. Like a less powerful but still effective Rainman. I have already been told in no uncertain terms that I am not allowed to play Blackjack at 2 of the 3 casinos in Mesquite Nevada, which pretty much proves that I am a winning player. I also think that being LDS gives me another advantage since avoiding alcohol and drugs is second nature to me. Both of those things are associated with casinos, and both of them would throw off my mental game.
Why then, does the Church oppose what I do? I do this on certain weekends in addition to my weekday job. On my weekend in Mesquite, I visited the YSA Branch. I told everyone what I was doing in town. One of the Bishopric Wives told me "Oh, you don't want to gamble dear." A couple of the other guys in the Branch however, were pretty impressed.
Also, I have a running joke about how "You can trust the Bishop's investing company right?" Referring to the fact that affinity fraud is rampant in Utah and that sadly, anyone scammed by it would have been better off going to Vegas and putting it all on red in Roulette. Or even better, used it as a Card Counting bankroll.
