Are you down and out? Are you on the street? Does evening fall so hard that you’d like Paul Simon to comfort you? Fear not, brave soul. Moka has some content for you. Moka is an odd SMS service that condenses and sends the key thoughts from many popular self-help books (Louise Hay’s “You Can Heal Your Life,” Wayne Dyers “Inspiration,” God’s “The Bible”) and sends them to your phone.
