Experience has many names. But I guess what it comes down to is that everybody knows only so much. Another way to put it: Everybody knows a lot of some things, but nobody knows everything.
Screenwriter William Goldman is famous for quoting, "In Hollywood, no one knows anything." In other words, he's referring to the fact that there are no perfect filmmakers or celebrities or movies or ways of making movies in Hollywood. Yet, there have been landmarks within the industry throughout the past century in terms of the technology that has developed and become useful. Along the lines of only knowing so much at a given point, this is where I'm at far as my experience with job searching, working, and applying goes.
For those who are in a similar area, remember that this is a process. Don't merely look at it as a series of end points and new beginnings (which isn't entirely a bad thing, mind you), but as a transitional and learning experience. Look at what you can learn from previous experiences, whether they involve family, work, social time, recreational activities, or what have you.
Here are a few transition-related quotes I found on thinkexist.com:
“Nothing is secure but life, transition, the energizing spirit.” ~ Ralph Waldo Emerson
“We live in a time of transition, an uneasy era which is likely to endure for the rest of this century. During the period we may be tempted to abandon some of the time-honored principles and commitments which have been proven during the difficult times of past generations. We must never yield to this temptation. Our American values are not luxuries, but necessities - not the salt in our bread, but the bread itself.”
~ Jimmy Carter
“The best performance improvement is the transition from the non-working state to the working state.”
Still here, and progressing,
