sometimes, you have to take a deep breath and just dive in. yes, you might drown or encounter some kind of poisonous serpent or a new species of eel with sharp teeth. but imagine the excitement, the accomplishment, the pride you will feel when you find out that your lungs are actually gills and your hands are actually webbed tentacles. so get in there. get in there as fast as you can.
