Seize the moment, friend! What you can do NOW with that 10% slice will never exactly be on your possibilities map again.
Physically, I don’t feel a lot different than in my 40s. ( I’m pretty firm in my exercise schedule. ) But looking over almost anyone in their 80s, I’m reminded that the 60s likely kicks off ‘the fourth quarter’, to use sports parlance.
Time to let it all hang out, leave nothing on the table.
