So true, thank you for saying that Natalie. Whatever knocks we take along the way - whether trad or self-pub (or both) - it is so important to see these as learning experiences and will only ever make us better writers (for ourselves and our passion for what we do as much as for career success) and to become those better writers we just have to keep at it!
I have learned so much from my first experience of writing a novel and self-publishing it. It's been such a learning curve that has given me a great deal of satisfaction and that alone makes it worthwhile, even if there are some lows along the way. In fact, the very resilience it is teaching me is such a valuable quality to have if I'm to continue to write and to seek publication, or publish independently. Resilience itself is something that only develops and strengthens if you keep going.
