...is one of the most frustrating things about this job, but sometimes also the most fruitful. I'm usually not the number one priority of a client or person I'm interviewing or source, which means sometimes I have to wait quite awhile to get even a quick response to my messages. I treat following up with great trepidation, waiting as long as I reasonably can for an email from them I know will never come. I actually schedule follow-up dates in my to-do list and "snooze" my email threads until then so that they're not cluttering up my inbox. It can test my patience, but that patience can really be rewarded. I waited a week after a client told me I'd receive my payment for services rendered to remind her, and also mentioned that I'd love a chance to work with her again. I received pay promptly and even got a referral to a new client offering more work that the one who referred me to them. So yeah, taking your time can definitely be worthwhile.
