You are here to do great things. Your great things are not necessarily the same great things that the person next to you is here to do, and they are important, nonetheless. Your great things may not be obviously life changing, and yet they are. You may not consider holding the door open for someone, or being the best parent you can be, or having a knack for making people comfortable to be great things, and they truly are. Remember that you and your deeds are important in this world.
