+1 to lhamo's advice. I could not do any better. Take your vacations when you want, or quit and take them. My grandparents traveled late in life but it only made my granddad encourage me to travel more, younger. He said it gets harder to move around, you don't enjoy it as much, and he pointed out that the friends you'd planned on traveling with have a way of dying on you. Take those trips, with those people, while you can.
Most people will tell you to keep working. They don’t know anything else. You seem to have several times more than what you need.
Margarita, I could hug you. My husband left his job a few weeks ago and we'd planned for me to keep working. I’ve worked in tech for 20 years, since I was 18 (I worked full time while going to college full time). We made this plan out of fear: we are FIRE safely, and others on the forum have helped re-convince and encourage me. But for neither of us to work seemed Just Not Done.
An upcoming business trip was my breaking point. My company has these horrible engineering "work weeks" twice per year (it used to be every two months for the project I'm on), in which they fly people in from all over the world, sequester us in a hotel, and have us work intensely together for 12+ hours a day. At the one in Dec., due to executives causing an absolute s**t show, I worked 14-20 hours/day for five days.
It came time to book travel for this next trip, and I could not physically bring myself to it. I know it sounds bizarre, but it's like my hands wouldn't click the buttons. I was having panic attacks just thinking about it, crying on Sundays, etc. It really is like I have PTSD from the job and that last trip.
Nope, no more. Resigned to my boss last week and the rest of the company gets notified tomorrow. I’m not going to have Stockholm Syndrome. For 20 years a lot of my identity has been wrapped up in being a techie with other techies, the shared skills, language, history, practices, culture. But it’s toxic and I need to save myself. I really do feel like I’m escaping an abuser, though I know it sounds dramatic. The stuff about planning, shredding papers, etc. really resonated - this stuff is like plotting an escape!
