Professionals
I really adore professionals. Because these people can talk about their beloved affair with alacrity and inspiration for hours. In my opinion, it is much better when man can do something good than be a "master" in everything. For instance, joiners. We all love good made wooden things. However, how many refinement a master has to know to create such a good table or bureau.
I guess, my text is full of russianisms, right? ;)
