Self-doubt as a Writer

Self-doubt is something I, along with many others, experience on a day-to-day basis. In fact, the only reason I held off from creating a blog until now was because I didn't feel that I was good enough. I am constantly doubting whether my writing is of the same quality as others, and I know not to compare my work to others (we all have different styles after all) but it doesn't stop me from thinking that what I produce isn't as good as it could be. It is for this reason I suppose, that I hesitate before calling myself a writer. Instead, I call myself an aspiring writer. The word aspiring leaves some wiggle room. It clearly shows my aim, but leaves enough space for improvement.
