Self-help Audio books are a great tool for education. Self-help audio books range from public speaking, to learning meditation. Self-help books are used to develop one's skills to be happier, smarter and more successful in life.Self-help audio books are a valuable learning tool because of their format. You can't read a book while you're driving, can you? Self-help audio books let you learn new things in many places you couldn't previously. Imagine learning anew skill while you are doing laundry, driving, exercising or going to sleep.For this 'miraculous learning' to take place, you need to listen to the book several times. This is for the information in the cassettes/CDs to be absorbed fully. However, it's very easy compared to reading a book many times. Some estimates say you should listen to self-help audio books 21 times in total to fully absorb the material. This can be easily done merely listening 3-4 times a week until the information becomes second nature. An audio book heard only once will most likely disappear from the memory very soon as like any other sound heard only once.
