My transition method (back around the turn of the century, eek!) was to preserve my source of income until all my "passing" procedures -- electrolysis and facial surgery -- were paid for, and my voice was properly retrained. So I compartmentalized my life. I slowly went full time in various social milieus, depending on where I was with my physical changes. Support group, sure, I was full time right away. And shortly after that, at home with my supportive partner. By the time I went full time at church, I'd had 9 months of electrolysis, and several months of hormones -- but more importantly, I'd found and developed a female voice. A year in, full-time was extended to immediate family (extended family was held at arm's length for several years after transition, for other reasons). All my "past life" friends had dropped away, so that wasn't an issue.
At 16 months, I had facial surgery. That, frankly, was good enough to get my letters for bottom surgery, even though I hadn't transitioned on the job. Two years in, I had bottom surgery and BAS. And then I did the most audacious thing -- I quit my job, rather than transition there, so as to preserve my narrative privacy (so only one person at work actually knew, that person being my boss, and he was very accommodating). Instead, I moved away, and started a new life. In poverty, at first, sure, but so what? It didn't take long to get new work, as the woman I was, without any hint of misgendering whatsoever. No narrative issues to deal with. I was free. And I still am.
Here's the thing -- it's impossible to tell how going full-time is going to play out at work. So many go full-time before finishing electrolysis (let alone facial surgery), and then lose their jobs or quit because of misgendering -- and from here, it's like being in a vise, because it's so much harder to rebuild one's income when one is visibly gender-variant. It takes money to get zapped, and to get bones rearranged.
It's the zapping that's the worst, because it also takes time. A good couple years, yes, but in day-to-day life, it takes time to grow out hairs so they can be identified and killed and removed. And during those couple of days, it's going to be dysphoria-inducing, and socially problematic (if being gendered correctly is an actual concern). If there's any bit of advice that anyone listens to, listen to this: before coming out at work, at least get to where your zapper can clear your whole face in 2 hours or less every week. Once you get to that point, you can start growing out on Friday, get zapped on Sunday, and get back to work on Monday not too worse for wear. And even better if you can get through the week without shaving at all (it's so hard on the skin).
If you need facial surgery, seriously, get it done before going full time at work.
So what does this all look like in hindsight? It's basically making yourself a cocoon to live in for a couple years. Whether you're a moth or a butterfly, emerge from the cocoon too soon and your wings will be too fragile to fly. You might still be able to muddle through (many of us have, by necessity), but it really doesn't make anything any easier.
Well, except, perhaps, your dysphoria. Which is usually what drives this whole mess anyways.
