Your biggest opportunity probably lies under your own feet, in your current job, industry, education, experience or interests.
Brian Tracy

My first six years in the business were hopeless. There are a lot of times when you sit and you say "Why am I doing this? I'll never make it. It's just not going to happen. I should go out and get a real job, and try to survive."
George Lucas

Replying to all resumes would be the polite thing to do, but often it simply isn't practical. If a company receives 200 responses for an ad, or experiences a continual deluge of unsolicited resumes, it would spend an inordinate amount of time sending acknowledgments. If you really want a receipt for your resume, send a stamped, self-addressed postcard asking for one. If you make it easy, the human resources department will comply.
