I'm 43. Single (happily divorced, but no kids and came out fine financially).
Mortgage under 150k, but locked in at 2.5%. Did treat myself to a boat and a vehicle in the last couple years but those will not go to the full term of their loans.
401k and IRAs (as of close on monday) all together were about $380k. I check in on them at least weekly, and set a time once a quarter to make minor adjustments. To be conservative, annual deposits are $25k (not counting about $2500 in annual dividends in a self managed part of one IRA that are in DRIPs). Did start an HSA a couple years ago, gets about $2500 a year put in it.
Short term goal (<18 months) is paying off vehicles. After that, trying to decide if I just should maintain current course...or if I should just start throwing money at the mortgage, or build up a non-retirement investment account. Don't have a firm retirement age in mind. Would love to start kicking it around at 60, maybe shift to a lower paying retirement gig around 55 if I've had enough of my line of work...
I haven't shifted to an advisor yet, but its something I've considered. Have a guy trusted by numerous people in my profession who has done well for all of them, but don't necessarily see a need in going that way until I'm at $500k (or if certain mostly non-cash things come up after settling my parent's estate hopefully several years down the line).
