I try to say to students tackling the course, not to simply produce an assignment, send it in for me to mark, and then move onto the next assignment. And for all writers having a go at a new area, or genre, don't let despondency set in after your first attempt.
The first time we write an article, short story, poem or novel, we're learning. But, that's the start of the learning process ... not the end. So, if you write an article and it gets rejected, that doesn't mean that you can't write articles. It doesn't mean that the idea wasn't suitable. It simply means there's still a bit more to learn. So, have another go. Review what worked and what didn't work with your last project, and learn from it ... then have another go. Put what you've learned into practise.
Don't put it to one side and say, "Oh well, at least I had a go." Just because that first travel feature didn't work, it doesn't mean that the next one won't. Have another go. And another. And then another.
