Made account special for posting here. Late 30s. Two step kids. T-levels normal. I've been practicing RP for many years. Sucked at it for most. Posted a few times and got righteously massacred.
Finally getting my shit straight. Frame is up and running but not perfect. Body looking better but not mind-blowing.
She is responding well to the changes. I can see the fruits of my labor every time I make an improvement. Good stuff.

My question:

I think I might be a low-ambition guy. Not lazy, but just satisfied to do my work, hobbies, and repeat. Is that a valid thing to be? Can a man pull off this lifestyle with a definitely high-maintanance 7 / 8 hotness woman?

More detail:

[I'm not lazy. The things I do, I do a good job at.]

I'm an art guy. But my stuff doesn't sell. I tried aggressively most of my life to monetize my talents, but it never took. Could be my own lack of marketing vigor, or just a bad hand, or both.
Either way, I've come to accept that I love making my art even if it will never sell.
Yes I have the talent to make more marketable art that might sell, and I have some in the works, but the spirit doesn't move me to work on that stuff much.
The wife has openly expressed frustrations with this stuff.

We are both ideologically, politically pro-family. She is s SAHM.
I could probably get her more on board if I could give her a baby. I had the surgery this year to make that possible, an incredibly expensive ordeal, and after all of it, it may have failed. Still not sure, but looks bleak.
This further demoralizes her, and I'm sure she thinks she's attractive enough to go land a fertile guy while she still has eggs.

My job is only good enough to pay the bills. I'd have to retrain and change careers if I want better. But I'm comfortable. Not really keen on spending the time and money to go to tradeschool at nights. I've thought about starting a business, but it doesn't really click and I lose interest.
This is another area she has expressed frustration with. Her needs seemed to be more simple years ago, but now I see her longing for more material possessions and pining over shit in magazines designed to make women jealous.

Of course, she is no better than me, and not a very motivated SAHM, and just gets by.
I'm pretty sure she resents the traditional direction I took the family in, even though it's inline with our rational side (hers being ephemeral I know.) It's been SO good for the kids. I'm very proud of how they are turning out. Except when she has random anger explosions at them, and I see the looks on their faces like they want to kill her.
I think she fantasizes about breaking the family up, throwing the kids to the wind, so she can monkey branch to a guy with more resources so she can have the dream life.

Lately I've noticed she's upped the crazy in what looks like an attempt to make me crack and give her an excuse to say she was once again abused or some shit.
