How much do you guys have to be pulling annually to feel that you have been successful by the time you're 40? I know of course everyone would like to be making $20mm annually, but that's not what I'm referring to.
How much to the point where you would feel satisfied with your earnings power, and feel both realistically and mentally secure for your future/kid's futures (if you plan on having any)? Baked into this is of course things like vacations, multiple houses, private school, etc.; whatever expenses you feel are relevant.
