Today is day 2 and I'm still feeling blah :( I've been trying to promote my first book like crazy and I get very impatient. I've decided to continue writing the stories in my head and continue to promote but not as aggressively. When I write my stories it's like I'm watching a movie in my mind. I enjoy sharing my writing with friends and getting their feedback.
Everyone goes through periods of doubt, but I think if you really believe in something you should pursue it to the fullest. Do it for yourself and if you have children do because it's a life lesson for them. Keep on knocking on doors eventually one will open.
