yeah that sucks...
let me share something I cam across today in my study;
"Nothing is more grievous than the disappointment of a raised expectation, though not in the thing itself by a denial, yet in the time of it by a delay: Hope deferred makes the heart sick and languishing, fretful and peevish; but hope quite dashed kills the heart, and the more high the expectation was raised the more cutting is the frustration of it. It is therefore our wisdom not to promise ourselves any great matters from the creature, not to feed ourselves with any vain hopes from this world, lest we lay up matter for our own vexation; and what we do hope for let us prepare to be disappointed in, that, if it should prove so, it may prove the easier; and let us not be hasty."
I have learned this first hand after getting rejected for jobs after several interviews.
Finally, I stopped getting my hopes up and just go and see what happens... I am not so good at getting hired, but at least I do currently have a full time position, just not my ideal place to be.
