Yes, accumulation is mesmerizing, and addictive. It makes me not want to spend money anymore (along with my wife [humor]). But I'd reiterate what KimCDougC said...balance in everything! You never know what life will bring your way. Enjoy some of the next 8 years or so. I had a friend who was planning to retire on Maui at 50, then BAM! He was broadsided while driving in SF, and ended up with two steel rods stabilizing his spine. He's doing ok now, some 20 years later, but is a bit stiff, and the accident has limited what he can do in retirement.
