In the waiting line

We're always waiting. For everything, we wait. How many times a day do you wait for something? I wait for my alarm to sound a second time and for my parents to "really be serious this time" about me waking up, and I wait for my ride and for each class to be over and for him to text me after practice and who knows what else. And then there's the other kind of waiting. The long term waiting. We wait for our diets to start working and for us to lose weight, and we wait for the guy of our dreams to come along or for him to come to his senses and want us back. And usually the line for these things is endless. But even on the off chance that we do actually get those things, we wait for the bottom to fall out. So why? It's like we're waiting to be happy. But why? I've heard endless times "Good things come to those who wait." And that seems so stupid. What if I don't want to wait? What if I just want to be happy now? Does that work? Can we ever just get out of line?
