Pocket Change is a book of wisdom accumulated through life's challenges to make you think. The choices we make are not only crucial to our lives, but to others as well. For this reason alone, we should be considerate of each other. We many times question our existence because of the strenuous task we encounter. One thing to remember is every problem has a solution. We must always search ourselves for error, that we may keep an open mind to the truth. This is the responsibility of life. As one needs pocket change for a parking meter or a telephone call, wisdom is needed as well as knowledge.
