I had been either working or studying in the arena of finance for about 10 years before my career change. So, I've spent plenty of time looking at investment strategies. The PP is pretty much the only strategy where I've been able to put all my money into it and not worry one iota about the broad economy and markets; or reading balance sheets; or looking at the current CAPE.
With the exception of my recent Bitcoin post -- which was really just water cooler talk, I just don't get any nagging feeling about changes or tilts.
It is often hard to tear ourselves away from numbers when it comes to investing. That data is just there, and ready to be consumed. However, numbers in investing are not like numbers in Newtonian physics. The system is not deterministic, and a lot of "art" goes into the process of deciding on an allocation. The obsession with numeracy in the field leads to all sorts of tortured discussions about tilting slightly this way or that way. And this comment is coming from someone who likes working with numbers.

I think it's okay to dump numbers to a certain extent, and recognize that the PP gives something more important: peace of mind. I'm thinking that a lot of other members here were drawn to the PP for similar reasons.
