So, I've always wanted to be an astronaut.
And now it turns out I meet the CSA's minimum guidelines.
So I applied. The odds of getting in are not very good, but - don't ask, don't get. And now I can say - hey, at least I tried. Because it's a shame to let a dream wither on the vine simply because you were afraid of being told "no".
Which is also what I tell myself each time I get a publishing rejection.
