The solution, first with the upper half:
Count the punctuation marks at the end of the five sentences in the upper half. You get 13, 15, 18, 19, 5. These numbers, when attributed to position in the alphabet, give M, O, R, S, E.
Now look at the second half:
The words go from lower case to ALL CAPS and then back again. One might say that it literally looks like how morse code looks, with the short and tiny dots packed together with the higher dashes. Combining that with the punctuation hint at the final line (similar to before) we see that there are 20 1s and 20 !s; and there are 20 words in the second half of the hints. One of them means something, and thanks to a recent edit to the question, we can see that the "1 represents enumerations". So I'll ignore the !s.
So where do we go with this?
The 1s enumerate this sequence of numbers: 4, 3, 4, 4, 4, 1. If we apply that sequence to represent the length of individual letters in morse code, and use lower case words as dots and upper case words as dashes, we can construct a morse code sequence: .--. ..- --.. --.. .-.. ., which translates into P U Z Z L E.
