Welcome to the forums Trent! Quite an impressive introduction. You should not be too scared about failing. Failing means your running a business, get over it. Keep trying and you will be succesful eventually. You can learn quite alot here if you actually do something with it. Most people are willing to help with your qeustions aswell.
Also, Kindle has ALOT of competition, so it would be quite hard to get on top of it. There are numerous ways to promote a book (look at this forum for example!), and Kindle is one of the worst in my opinion. When your actually ready to produce something, you can publish small pieces here, im sure people would be willing to proofread small fractions of it.
