What do you want to do? You can do everything, from starting with exercises, prompts and improving your skills, to trying to come up with different ideas (since you have no desire to write any of the old ones), or, well, persist with the old ones (treat it as work, not fun). If you decide to persevere with those one or two that are an exception, then you can start with some fun worldbuilding, or coming up with things for your characters to do, or inventing baddies, or trying to outline the plot, even start from the end and work backwards. Or, none of the above. Go watch a movie, take your mind off writing, relax, get in the right mood, wait for more inspiration.
