比如有人说，"There are no experts, only specialists"。 Freeman Robert 这么说：

1. There are things I never quite understood right.
2. Things I didn't know that I thought I should know.
3. That there are things that I knew at one time, that I completley have forgotten (I hate this one the worst I think).

也有相反的 Connor McDonald (http://www.oracledba.co.uk/) 比较狂:

I've always been an expert...Its just finding exactly what precisely I'm an expert in, that's the challenge

Jonathan Gennick (http://gennick.com/)更为赞成:

I have expertise in writing SQL queries

这样的说法，因为一旦说了

I am an expert in writing SQL queries

这样的话，会被人误认为

I know everything there is to know about writing SQL queries

多数人还是不敢称自己为 expert ，不过也有人承认，在商业场合，可能是另外一回事了。
