You are certainly doing very well, but, at your age, many variables, as have been previously mentioned, must be considered.
In my age group (50’s), generally speaking, I agree with $2MM–excluding real estate–especially if you plan to retire in CA. For those in their 30’s, I would think $3MM+ might be more realistic, especially since I’ve heard from younger friends, that many financial planners today are telling their clients in their 30’s and 40’s to plan on $0 Social Security and Medicare.
The trick to all of this, is, of course, to actually get to retirement–the next phase of life, or whatever each of us might choose to call it with these reserves still intact, and the health to enjoy life at that particular point it time.
