Banishment this world!
. Also, I suppose I'll be slightly reluctant to delay my novel completion date (I'm a slow writer already, as you know) to make time for the stories.
Way I see it, finish your book first and start submitting it. While your sending it off to publishers/agents and waiting for responses, work on the other stories in your world.
If you don't get bites for your novel first time around, maybe the publishing credits from the short stories you did after submitting the manuscript will help for your second attempt, once you have revised and improved upon the manuscript.
