The Spencerian script has a reputation for being one of the most beautiful writing styles and one of the easiest to pen down. The fifty-two-degree slant is carefully chosen as it provides the best writing speed, and the seven basic strokes to form all the letters add to the convenience of this system. Once you've mastered these basics, you can develop your style, especially in the curls of the capital letters.
There is much to be said about handwriting, or writing with pen and paper. The human brain processes and stores according to its constitution and capacity. Language and writing are critical to all of this. So, in short: "writing is important." You may take that seriously.

The booklets, from 1 to 5, contain instructions and example words to copy on the relevant line markings. Practice makes perfect, and that also counts for writing.
