Learn to cook. It's a useful skill and the reward is delicious.

I myself have finally found time to continue with my fan fic Written about 1500 words in the last two days bringing my short fan fic up from 8500 words to 10K words in total. A tiny milestone but a milestone none the less XD A hobby where I get to practice my creativity and where I sharpen my grammar and punctuation. All while I sit down and move nothing but my fingers. Got a long way to go before I can write anything real though.

get involved in politics

deus ex and system shock 2. there is no game better FACT!

Modding Skyrim.

You could pick up an instrument. 3 months isn't going to make you amazing at the instrument but 3 dedicated months should give you a great foundation and there are plenty of online guides/courses.

If you don't have the money for that maybe you could try woodworking/carving? It's an awesome skill to have and simple kits for it can be acquired fairly cheap. If you need any machinery for any project you pick up you can rent it for a day and it won't cost much more than lunch.

Another option along the same lines would be to study plumbing/electrician work/basic mechanic things/ect.

Life skills like those are probably the best way to burn time if you want to feel productive. You will use them for the rest of your life and being able to fix things is always a selling point with the ladies.

Attempt to moderate (5-1)chan. Should keep your hands full.

A girl won our schools poker-night tourny (100 competitors). She isn't a girl with a brain and thus, I cannot understand how she could beat an IB-math genious in a 1 vs 1 poker final. She admited she's never played poker before. Skill, my @$$.

I can't really explain that. You can't simply walk in a huge poker tournament and win the whole thing without any kind of experience or knowledge, unless all of her opponents svcked.

this is literally the worst suggestion for a hobby ever made

What do you have against him? Do you not realize that what you are saying will make anyone commit suicide? It's... it's insane!

On topic, reading is good.

What the hell does poker have to do with math? Unless you're the friggin' rainman, you can't do all those calculations in your head anyway, so it's just how you play your hand. Knowing when to fold, when to raise, how much to raise to seem threatening or tentative, and how to read your opponent(s) is what it's about.

Edit: Or sheer luck, of course.

the math genius got lucky, thats all

Sheer luck, there we have it I can't answer how much math matters, but the picture I was trying to paint was a final 1 vs 1 where a geek meets an anti-geek and the anti-geek wins. What were they playing for a game? Doesn't sound like poker to me.

You know what. Just play Magic: The Gathering for money instead I say. In that game luck is by far a smaller factor, you still need to be able to bluff your opponent in some cases making him fall into your traps and if you draw a bad opening hand you can mulligan for a better one making the game more skill based than luck based. Especially since you build your own deck so no two players are playing with the same cards.

Only problem is that by the time you win your first game for money you realize you've already lost to Hasbro and Wizards of the Coast since whatever you earned is probably less than how much you payed for to get the cards for your deck.

HO slot cars. When I was growing up I loved them. Now I'm in my mid 30's and I still love them. But now that I'm older I find myself getting them to go faster. Growing up I had but a few. Now I have two dozen cars and I still buy them. Last car I built was a full race G3. This car is so fast that it won't even run on my track cause I don't have enough power for it (my track is only 13 volts, this car needs 24).

OP, slot cars are fun, go buy yourself a cheap track and a couple of cars and start tinkering. Just watch out, they get expensive as you get into the performance end of it. The G3 I built was around $100 the last car before that was an old "Wild One" circa 1968 and that was about $80 to build.

It'll keep you occupied.
