Review all my insurance policies to make sure they are adequate. One big loss or lawsuit could ruin everything.
Keep a little more in cash, just for my peace of mind.
Update my power of attorney form.
Exercise more and eat healthier.
Meet with my financial planner and discuss this very topic - what more should I do to protect myself?
Continue LBYM - maybe even turn it up a notch until I get comfortable with retirement. However, I'm not skimping on the important things, like medical care, heating/air conditioning, and other safety expenses. My late father always said "don't skimp on tires or brakes". Smart man.
Having said all that, it's impossible to know exactly what the future may bring. While I want to be prudent and make sure I don't experience major losses, I don't intend to spend a whole lot of time worrying about every little thing that can happen.
