From the early days of the telegraph, to be a telegrapher was a job, and there weren't many of those folks. They could recognize each other's style by their dots and dashes.
The style is the man. Rather say the style is the way the man takes himself; and to be at all charming or even bearable, the way is almost rigidly prescribed. If it is with outer seriousness, it must be with inner humor. If it is with outer humor, it must be with inner seriousness. No other way will do.
Under the bright sun, many of us are gathered together with different languages, different styles of dress, even different faiths. However, all of us are the same in being humans, and we all uniquely have the thought of 'I' and we're all the same in wanting happiness and in wanting to avoid suffering.
Let us guess that whenever we read a sentence & like it, we unconsciously store it away in our model-chamber; & it goes, with the myriad of its fellows, to the building, brick by brick, of the eventual edifice which we call our style.
I might say that what amateurs call a style is usually only the unavoidable awkwardnesses in first trying to make something that has not heretofore been made.
