best poker format if you want guaranteed income not just variance?

most of the guys i know talk about tournament glory, but honestly i'm a lot more interested in something steady. sitting through a 10 hour session only to bubble is brutal, and i'm not into sweating my rent over an all-in. i get that cash games are supposed to be more “guaranteed” if you've got an edge, but the swings still scare me and it's not like you can clock in and clock out with a paycheck.

been thinking about things like sngs or maybe double-or-nothing formats, but it always seems like rake eats up any margin. some of the regs say limit games are the “low variance” option but those look like a grind and the pots are tiny. does anyone actually have a format or schedule that’s mostly winrate and not just luck? or is that just a pipe dream and variance is king no matter what? curious what other grinders have landed on to keep it sane. is there really a safest seat at the table, or does it just not exist?
