I've recently updated my FIRE plan. It used to be much more vague, but now I've set an exact date for when I want to go very part time/ semi-RE. This will happen no matter whether I've reached my target number - I figure that my expenses are so low that I can sustain myself even with 40% work, so the portfolio can just keep growing.
In terms of accounts, I check my investments about twice a month and make a detailed list of my net worth once a month (at the moment on the 'Race to 50k' thread). My current account I check every day because, being self employed, I usually get payments coming in 3-5 days a week.
