Jumping Trains

Okay, so the last week has probably been full of some serious contemplations. Let me draw a little metaphor for you, if I may....
I am on a speeding train, going one direction obviously, and the destination is pretty great. Heck, the train is pretty nice too. It's a sweet setup. No lie. However, I don't find myself looking forward to actually getting there, despite all of these great things. But the train is moving too fast...and it's not stopping. Suddenly, I look over and see another train, going in the opposite direction. Let's be real, it's not as nice. In fact it looks like a pretty bumpy and rough ride. But I find out what the destination is and I realize I want to be on that train. I want to get there, even if the trip is going to be awful. I want it so bad. Here's the catch: I have to jump and I am scared out of my mind. Both are moving fast, there is only one small window of opportunity to make the switch. Everything I've ever known is already on the train I'm on. Everything I am terrified of and don't know is on the other. So here's the question: Do I jump and end up with my guts splattered on the tracks, stay on my own train and be content with the status quo, or somehow make it to the other train and get something I've always wanted? I hate deciding.
