While you are drifting along this timeline, those you leave behind, those who will join you in the future, will either add something to you or take something away from you in a way that you cannot comprehend, and will be deleted from your life. Everyone is always where they need to be, when they need to be. Those who left left because they had to go, the rest are with you for a while. Even if where you are is not where you want to be, if the things you want don't happen on time, maybe it's because you're not ready yet. You can't just stand still, and you can't live every moment all the time.
