Let's see. As near as I can recall, I've held the following “entry-level” jobs during my life:
1. Potato peeler
2. Paper boy
3. Lawn boy
4. Farm hand
5. Garbage man
6. Warehouseman
7. Private (USMC, retired)
Each provided valuable experience.
I have a couple of those and even drove the honey wagon occasionally as part of a campground maintenance job.
