Starting a new story in Thoughts on thoughts

So, I’m beginning to start writing a new story. I had these notes for it back a couple of years ago and didn’t know how to go forward with it. I am actually thinking it may be a good short story idea. I am thinking if I can get myself to write again with just short stories in a full book I may feel a bit better about myself. I love writing but I am so judgement on my own work that I won’t even let a stranger look at it.
Being outside of myself and looking into something else and maybe creating a whole different life has always been something I’ve been interested in… I just hope this idea will work. So far, I have three story ideas… that just need some middle and endings to them! We’ll see what happens…
