Please let me know if there are things I should be thinking about other than what is discussed above.

Try going reduced time if they will let you. I'm not the biggest fan of my job but to be totally honest I got a little bored at about 75% time. Not working full time at least in my case made work a lot more tolerable. Like WAY more tolerable. Also they might jump at the chance to get someone in and not pay them benis or have them just work during the busy time.

If you are going to quit anyways it isn't like getting fired is much of a threat.

Just maybe something to consider. That said I'm about 10 years behind you and I hope to be in about your same spot in another 10 years so my opinion might change. I consider myself FI in that if I live minimally or work for min wage my lifestyle really won't change.

I love to travel but I think if I did it full time I'd grow not to like it.

I'm dept free basically at the moment and I'm just piling funds in the retirement accounts right now.

SS will still be around. They aren't going to toss everyone on the street. The trust might be bankrupt but they still can pay 70%.

I'm not trying to steer you out of being done working 100%. I'm just sharing that I did get bored. So if you got a good working relationship with your company maybe you can get something worked out. You could then slowly sell out of your funds but I guess I don't know your situation.

For example you could maybe go reduced time, max out the 401k and then slowly roll stuff out of the taxable. This would reduce your tax burden. For me the 401k and Roths are a huge part of my strategy.

Also I'd consider talking to a lawyer about a trust. In my state 401k's and Roths and primary residences have huge protections. It would make me a little nervous having 1 million sitting in a taxable but I'm paranoid about stuff like that.
