Some people lead their entire lives never realizing their full potentiality. The good news is there is still time for you to achieve greatness and to fulfill purpose in your own life. The reason you still have this opportunity is because the Universe has a plan for you. Once you truly begin seeking what lies within your true self, your hidden talents for inner peace and success start to take shape.
You may not personally have children but I am sure you have nieces and nephews, so that counts, too.
When we are willing to lift the veil of illusion about our purpose while on earth, we will be more fully prepared to see and hear the truth of our existence.
