Do u feel somewhat stuck??

Hi there..im new here and i have had a tour of this site and i must say i really am impessed wiv all that is going down here. I however am at a strategic point in my career now. I kinda feel im not at the place where i would be at my best though this could be said to be wat i had always dreamt of being but now the dream is realised, i kinda feel i dont want to be here anymore. Scared tho to look elsewhere.. and dont know if the world there has a place for me in my preferred field now..Great minds, wat do ya think??
