I decided to start a thread for basic help in writing and feel-good reminders. Eventually I will post a totally awesome list I came up with in high school, but for now, I will give you a quote from the 2010 edition of Writer's Market. (For those who don't know, this book is a great resource for writers who are in the publishing stage.)
This goes for critics on sites like this, who are trying to help their fellow creators. I understand if you prefer not to be criticized, but we're only trying to help. If you don't want it, you politely ask for no criticism. I, for one, will respect your wishes. Either way, if you want to write, you should write! Who cares if you have a mistake or fifty. Your ideas and creativity are what matter. So keep writing, everyone!Take rejection with a grain of salt
Rejection is a way of life in the publishing world. It's inevitable in a business that deals with such an overwhelming number of applicants for such a limited number of positions. Anyone who has published has lived through many rejections, and writers with thin skin are at a distinct disadvantage. A rejection letter is not a personal attack. It simply indicates your submission is not appropriate for that market. Writers who let rejection dissuade them from pursuing their dream or who react to an editor's "No" with indignation or fury do themselves a disservice. Writers who let rejection stop them do not get published. Resign yourself to facing rejection now. You will live through it, and you'll eventually overcome it.
