Who am I

I am the rhythm in your heart, I am there in every beat. I radiate throughout your being, from your head down to your feet. I am everything you feel and everything that you are I am the dreams that you dare to dream, I am your guiding star. I am the life force that drives you every morning when you wake. I am the pride in all the good deeds that you chose to make. I am the spirit that lifts you when you are drowning in a sea of tears. I am the happy thoughts that distract you from your worries and your fears I am the energy that ignites you when you are struggling through the day. I am the words that you speak, I am present in everything you say. I am always there to steer you in every decision that you make. I take in the air that you breath, I am in every breath that you take. I am in all the happy days you have spent and all that are to come I am your first breath on this earth and will be the last when your work is done. Who am I ?
