Waiting for things…

I had a conversation with my mom last night regarding my sister and her wanting to find someone, some special guy to love. We discussed how it is unfortunate that many women spend way too much time putting their life on hold until they find a partner. I know of two friends that also have a hold on their plans until they become a duo. I started to wonder what I am waiting on, if anything… what do people in general wait on? what happens if this thing that they wait on never comes?
