Job Applications? Why bother?

I haven't decided if I am just inordinately lucky or if I have some kind of super-power but I realized when I was telling someone about my new job that not only have five out of my six jobs been great jobs but I've only ever even applied to one of them.

Jobs had:
Movie Theater
Music Theater
Amato's
Data Entry for the University of Maine
Book Store
Automotive

Job: Movie Theater
Acquired: Because my mother was working there when they needed to hire someone new and nepotism is something hicks in small towns do.
Pay: 50-75 cents above the State-mandated minimum wage.
Duties: Cleaning, selling tickets, doing concessions, changing the marquee, cash-up, inventory, answering the phone, talking to people.
Perks: Free movies, free popcorn, free fountain soda, cheap candy, ability to read while getting paid if otherwise not busy, Christmas bonus, time off if/when I needed it.
Downfalls: Customers who did not understand that it was a one-screen, customers who wanted to pay with plastic, customers who wanted to buy tickets in advance, the fact that the theater was sloped and not tiered and any soda spilled ran down hill, seven day weeks in the summer.

Job: Music Theater
Acquired: Because my friend was their regular light-person and he knew I could do lights (I used to for productions at our highschool where I learned by doing).
Pay: A dollar above state-mandated minimum wage at the time.
Duties: Lighting
Perks: Free dinner, free fountain soda, free shows, attractive actors to look at, ability to play Pyramid solataire (because it fit on the counter under the light board better than other versions) while working.
Downfalls: Lighting system occasionally overheated and flipped the breakers which made me have to quickly throw on the spot-lights, turn down the master some, and run and flip the breakers back on, I was not an official employee, I only worked when the regular person was off, and they tended to cancel shows without any warning even to me.

Job: Amato's
Acquired: I knew the manager and she agreed to hire me on the spot.
Pay: A dollar twenty-five above state mandated minimum wage starting out and was given a fifteen cent raise after three months.
Duties: Making food, prepping food, prepping vegetables, washing dishes, washing counters, prepping dough, taking things out of the freezer, lifting heavy things, sweeping, mopping, cash-up.
Perks: None. I didn't even get a discount.
Downfalls: Cameras, not allowed to eat food for free, no discount on anything, worked by myself primarily, did not get breaks because of the previous, was not allowed to sit down, was required to serve customers until nine but it took nearly an hour to close up and corporate got mad if I stayed after I was scheduled, co-workers, hot oven, cooking in a fast-paced situation, the grease that permeated everything, the cement floor, and customers.

Job: Data Entry for the University of Maine Acquired: The scientist my father had worked with on a fishing research project needed someone to turn physical logbooks into spreadsheets.
Pay: There was 1,200 dollars budgeted to pay someone to do the data entry.
Duties: Turn logbooks into spreadsheets.
Perks: Work from my own bedroom, task took a total of eight hours.
Downfalls: I couldn't keep doing it.

Job: Book Store
Acquired: By application.
Pay: State-mandated minimum wage.
Duties: Checking in books, magazines, newspapers and gift items, putting away books, magazines, newspapers and gift items, checking inventory in assigned book and magazine sections, straightening book and magazine sections, writing blog posts, making up displays and windows, helping customers find books, recommending books, checking people out, doing back-stock, some vacuuming and dusting, doing cash-up, and watching the customers.
Perks: Reading free books, discounts on store items, and talking to people who like books.
Downfalls: Dealing with customers who have no concept of reality, living with sometimes annoying coworkers, trying to figure out where to draw the line... for everything.

Job: Automotive
Acquired: Was informed of the job by a regular customer in the bookstore, told what it would involve, and was warned that the owner was very crude. I went in knowing I was capable of meeting the job requirements and confident that crude was something easy enough to deal with after living with a commercial fisherman for nineteen years.
Pay: One dollar and fifty cents above the state-mandated minimum wage.
Duties: Opening mail, using Quickbooks and spreadsheets, answering the phone, doing billing, filing, updating the website, updating the company Facebook, smiling at people.
Perks: Nice pay, relatively easy work, would make a good future work reference, have permission to read when not otherwise occupied.
Downfalls: There are no buses that go past there and I may have to actually get my license. I have yet to work here but I suspect that 'dealing with customers' is probably going to be the biggest downfall.

Those five jobs that I didn't apply for but got anyway compared to the fifteen other jobs I applied to before I was hired at the bookstore and the several other applications I sent places since then that I never even got a call back on... Well, it makes me think that filing out applications might not be worth it.
