No problem - since much of your plan details are not in this post and some of your figures are rounded or estimated the ability to do any checking or commenting on this plan is very limited. Without really knowing your savings, income, or expenses the feedback will have little value or could even be misleading (unintentionally).
Understand, I wasn't really putting it out there seeking specific feedback (though I always appreciate it when it comes), just responding to the OP w.r.t the question of lowering lifestyle to facilitate ER. I threw out a few summary numbers to indicate what I meant by lower cost lifestyle and convey that I wasn't doing something reckless like punching out at 55 assuming 10% returns and that a 6% withdrawal rate would last 40 years.
I did give my most recent current expenses: $31K ($31,400 actually) in 2016, which includes everything but income tax. I've been pretty stable at that level for a few years and content with the day-to-day lifestyle. I also gave a number that bounded my estimate for expenses in retirement that I'm planning for ($45K, with basic needs/wants being $33K of that, the rest for discretionary/leisure, and both those numbers are pre-tax equivalents). Didn't give my current income because it really doesn't matter, but it's on the order of 5x what I'm spending. I have no debt and already own the cabin I mentioned. I'll be selling my current home and downsizing (net of everything I expect to come out with $60K-$80K in my pocket after that, maybe more). My net worth right now is a little over the 7-figure threshold, with two more years left to fatten the kitty. There's a good probability I'll inherit on the order of $200K-$400K sometime in the next 20 years.
If the financial markets are not too terribly unkind, I should be in pretty good shape come 2019. Nothing is certain but I feel pretty good about the plan.
What I worry about besides vaporization of the financial markets is medical insurance costs spiraling out of control. But as long as my employer doesn't completely renege on the annuity and the gov't doesn't completely renege on SS at the same time (I can handle some reduction in either/both), I have room to increase my spending and still have, from a firecalc-style perspective, a high probability of avoiding shortfall. I don't have a ton of room to lower spending w/out it starting to hurt, but I have some.
Don't do something. Just stand there!
