We all have doubts sometime, but as long as we don't let them consume us there is nothing to worry about. Sometimes we fail. To err is human, wise men and women have said as much, right?
Doesn't mean we have to like it, but it does mean that we have to expect it and be ready for it. That was we can make its stay as brief as possible.
Time to suck up this little mess and move on.
Time to get back to writing.
