If you’re constantly doubting the words you write, you’re going to lose your inspiration. Because let’s face it, if we believe we’re not good at something, we won’t look forward to doing it.
Belief in yourself and your talent as a writer is what keeps you going. It’s what will maintain that level of creativity and inspiration and motivation you need to keep moving forward and finish your projects.
Push the self doubt away, and focus on what you have achieved. Focus on your best work and know that if you keep that belief going, you can achieve it again and again.
