But my ideas might be too far out there. -- Nonsense! If you hold back those unique ideas, you are holding back your true talent. Let people see what you can do. Put yourself and your writing to the test and make all of your ideas happen in your writing.
Stop over-editing! You know how it goes. You put down the thoughts or make a pitch and there is always something that is just not right. It's perfectly normal and necessary to go over your work with a fine-toothed comb. The editing process is needed to perfect your work. But don't comb it so hard, your writing is bald and flat. This dry, boring writing is exactly what your clients don't want because it's what everyone else is doing.
Where's the proof? Look around you. Think about all the successful writers you know. What quality do they all have? That's right. You will most likely find that they are all different. They take risks. They do things that the majority doesn't. You can't have average work and expect to have above average success. The math just doesn't add up. In order to succeed, you must put yourself and your writing out on a limb. Will you fall? Possibly several times. But those falls will help you learn how to build things back up one step at a time, with moire knowledge to take calculated, successful risks.
