"Obstacles are those frightful things you see when you take your eyes off your goals."
Think about it. If we knew how many obstacles there were to selling a book...or whatever your goal is....how many of us might quit before we ever gave it a chance? Goal setting is such an important part of reaching for our dreams. Set small goals: So many pages a day. Write one kick-ass query letter. Take an hour and research agents. Whatever you can do today to get closer to reaching your goal.
Don't think about the thousands of other writers trying to get published. Don't think about the small percentage of manuscripts that get accepted. Keep at it. The longer you write, the better you'll become. The more you'll learn. Keep your eye on the goal. And for heaven's sake, make sure you enjoy the journey, or what's the point?
And then when you reach that goal - make a new one. :)
