Some people claim to recall past lives as a person of great fame or notoriety. Such claims are usually greeted with skepticism, and rightly so. You, however, may actually have had a past life as a famous person, ruler or prominent person.
You come into this life with vague memories of past grandeur, and a strong sense of entitlement that it should happen again. Getting stuck in fleeting images of past-life vignettes will definitely keep you distracted from finding and fulfilling your true purpose in this life. Whatever that is, you can be sure it doesn't lie in dwelling on possible past-life fame. Instead, find ways to serve anonymously. Be a mentor to a troubled youth or do some tutoring in public schools. You've got plenty to give; just don't expect glory for it.
