Prior to you making the plunge to RE, how many times did you change your “number”? I am 2 yrs away from my latest launch date, but have found that I have moved the goal posts multiple times, particularly over the last 10 yrs. I have probably changed my number 5 or 6 times, doubling my desired number at this point over the last 10 yrs from what I originally set. I suppose much of this is due to a combination of adopting/learning more conservative withdrawal strategies and setting a more conservative AA, desiding I would like a little more discretionary income in RE, and perhaps some additional fear/OMY syndrome. Like most on this site, I have been working my plan for years and my exit time is still pretty much as I planned 15 - 20 yrs ago, but I now want a significantly larger nugget. I find it interesting how FI is relative and so different for so many people on this site. Some define their FI when they can generate $25K - $30K yr, others $250K - $300K yr. I suppose the person who is happy with $25K thinks the $250K person should have retired yrs ago and the $250K retire wonders how can anyone live on $25K? I would also suggest most of us want to replicate a standard of living we have been accustomed too during the re ent years prior to RE and not take real steps backwards so our FI number can move due to lifestyle creep. Aside from certain events which dictate a retirement before the planned date (I.e. health problems, lay off), I suppose we are all entitled to set our own definaition of FI.
