Owh~ That must be the reason!

I always wonder, why an expert always knows a lot in their specific work scope? I guess that must be the reason they are called an expert~ lol

I have been working as a Petrophysicist for a year, it cannot be deny that I still don't know a lot of thing, but sometimes, if I keep repeating doing the same thing, over and over like a dog chases its own tail, if something bad or wrong happen, I know where to look or at least to refer~

If I am doing this over and over for 15 to 20 years~ OMG~ that must be the reason~
