On balance I wish I had RE'd sooner. The last 19 months I took a job with an 80 mile one way commute and looking back its clear I was already FI.
Having said that, the really was one of those mountaintop experiences.. I.e the opportunity to lead a project that had never been done before.
When it was done I stuck around for a few more months, then I quit.
My numbers are all in my journal if your interested... Link below
