Surf Your Biowaves [EPUB ebook] 

With this book, one can calculate personal biograms and use them to improve the way one responds to the opportunities that life has to offer. By locking on to the rhythms which they demonstrate and becoming aware of the key dates they produce, one gains more control over the best timing for decision-making and planning or action. And there are many examples where the use of the biorhythm tool has resulted in phenomenal personal success.
