If there's anything you particularly have troubles on, don't feel intimidated to ask about it. I've been given plenty of good advice over the years with my writing and I've proven to be a very good editor and critic of works. I can totally understand that the hardest part is getting started, believe me when I say that. I think what matters most is to look at what you feel are some good stories and pick up the good habits those writers all share. There's nothing wrong with playing around with ideas you've seen from other writers. It's not always about thinking of something new. What you should do is take something people already know and make it your own. On a separate note, read what you write out loud, get second opinions, and don't be afraid to give it a second or even a third read through. Take breaks, too. Give yourself time to process what you have just written to let new ideas work their way in later on. Overall, be sure you don't get caught up so much on the little details that you fail to see the big picture. I, myself, have been guilty of that from time to time. Focus on what truly counts.
