WB - all investing is lay out cash and hope you get more back. You get Phd now and a bird in the hand is worth two in the bush doesn't impress ladies. If you need a computer or calculator you shouldn't invest in it. It should be obvious to you and then we act.
CM - the worst businesses I have ever seen use elaborate figures. Trouble is you believe it. They do that in business schools because well... they need to do something
WB - false precision based on std dec is totally crazy and it only happens to people with high IQs because you learned all this stuff and feel you have to use it. A terrible mistake to think higher math will help you in investing.
