I found this article in the Literary Hub inspiring – advising to aim for getting your work out there more often to magazines – get the envelopes, get the stamps, sort out self-addressed envelopes and post. (In many cases nowadays, submission is electronic.)
People who became successful writers later, often began with a systematic sending out of many manuscripts and being undaunted by rejection letters, persisting.
