Just a small update with good news. Josh has spoken to his grandmother about getting his part of his inheritance money in advance - the plan is to get it now and then not receive that part when they all "officially" share it. He has a brother and sister, not sure if I mentioned it earlier, and they all should agree on it. Surprisingly, his grandmother agreed. But he still has to talk to his aunt, and she's... bad news. We'll see what happens. If they don't agree, he'll go to court to get the money... but that will take ages... damn.
Anyway, the good news is he told me he wasn't going to invest the money in Poker anymore. He'll continue to play with the stash he still has, and invest whatever he receives into the Antique business. It's also risky, but at least he'll be buying goods, that are always of some value, not burning money away at the tables. I was very happy with his decision, not because he'll stop playing (he won't, for now), but because he's doing something different and that's the first step to get a different result.
Also, my stepdad will help him and train him and this is finally a way for Josh to learn "a trade" and start doing something that I consider "normal" for a living. Even though it's not 100% safe (what is, these days?) and it also requires investment, I look at it as normal, because that's what my step dad always did.
Next week he'll have an answer from his aunt. Fingers crossed.
