Carl Jung also warned that the occult are not to be trifled with and that I ching was not for amusement. It's funny I was just going through some notebooks from 4 decades ago when I was a young thing and saw page after page of questioning "should I do this?" "should I do that?" The misuse of the I Ching is an excellent way to lose your own independent judgment. Beware. (I made some poor choices based on misusing this book.)
Wilhelm's translation is indeed wonderful and for the thoughtful reader of the book, I strongly suggest spending time with 'Book Two' of his translation that focuses on Confucius' metaphysical commentary - it is profound.
Also recommended for the serious reader of the Ching is Richard Wilhem's Lectures On The I Ching - Constancy and Change, also published under the Bollingen.
A counter point is that if you are stuck in a 50/50 position, out sourcing the decision to some random other thing can break the dead lock. Like flipping to a random page on a book and going with the first word you see that is positive or negative (Bibliomancy).
The occult language can make it sound mysterious but it can also sometimes just be a cover for a delegation of decisions.
