"No human nature is self-sufficient, neither in words nor in deeds, and the best is the one that succeeds the most and fails the least."

Based on the above aphorism, I was inspired to write this book, knowing from the outset that conciseness and rationality are tools for all of us, today more than ever.

At the same time, two more of my books are available, containing grammar exercises. The first volume is closely linked to the present theory with direct references. The second volume is independent of the present theory for more advanced students. Both volumes are accompanied by inserts with the solutions to their exercises.
