According to Websters...
to allow or permit
to move or proceed, esp. to or from something:
Therefore, in essence, to let go would be to allow or permit [someone] to proceed to [a goal].
During the course of my life I have always considered myself an expert at letting go. After all, I've moved about seven times. However, today I have found myself facing something that I'm having trouble letting go of. As life is changing so rapidly right now, I'm having trouble letting go of people that have meant so much to me for so long. I think my greatest fear has been fueled by the misconception that to let go and to lose are synonymous. To me, to lose means the same as to fail. I think I have just realized that I couldn't have been further from the truth.
Growing up, when my family would move from one place to another, letting go was simple- necessary even. It's not hard to let go when there are no other options. Now, I am learning that I apparently know nothing about the art of letting go. I now realize how all the friends from my past would feel as I broke the news of my impending relocation and then left them behind. This feeling sucks.
I also realized that while I have been refusing to let go, I have only been inhibiting myself. People grow up, and as we do, we move on. Although this is nowhere near easy, it's necessary.
