It's hard, but it's not impossible

"Yahoo Inc. said it's chief technology officer Farzad Nazem would leave after June 8" The Wall Street journal(WSJ) reported yesterday. For those who don't know him, Mr. Nazem who often known by the nickname "Zod" is an Iranian- American computer engineer, and joined Yahoo Inc. since 1996. Then in 1998, his name was announced as the chief technical officer.
The important point is the reason of his resignation. "Mr.Nazem, 45 years old, described his departure as a retirement." The WSJ indicated.
Although this departure makes the gap among Yahoo Inc. and their competitors(ie. Google Inc., and Microdoft Corp.) bigger, Yahoo Inc. has predicted that it's revenue growth in this quarter stay stable.
I want to get some lessons! My goal is early retirement, and I should read Zod's biography to get some hints, but look at the Yahoo's stability. They lost two of their chief managers recently, but because the team is very strong, these departures have mere affect on Yahoo's shares.
That's power. Unfortunately, it's not wise to buy the big incorporation's shares; otherwise, I would buy Yahoo's shares for sure.
