When you feel stuck in life

You have the drive and motivation to get to your destination but once you are there – you’re left wondering – “what else could I have done? What else is there to life? Because if this is all there is then I’m not happy.” And, truth be told, I am not happy. I’d like to be something – more than just an office person. More than just someone who works that 8-5 shift. I feel like a complete wreck. Has anyone ever felt this way?
