Academia is all about the knock backs e.g. rejected papers, rejected grants, rejected conference abstract, rejected fellowship applications (weep!) et cetera! It's hard sometimes. We have to remember though that at this level, competition is **really** tough and there is no shame in not 'making the grade' every now and again. We can also take comfort in the fact that the peer review process isn't infallible and if someone has failed to recognise the genius in our work, more fool them! As you say, onwards and upwards!
