Welcome aboard. Learning skills is great, though to tell the truth, I'm getting a little too old to want to sleep in debris huts anymore. Still, getting to the mindset of camping to bring a mini-home with you to understanding how to live without all that stuff is a great first step. Consider the basics: first aid, shelter, fire, water, food, signalling/navigation. Pick a category and start to learn.
For first aid, there are great classes available like the Wilderness First Aid programs that are really worth the price and effort and can come in handy for all types of situations.
Fire, well there are million and one things to learn here that most people stuck on bic lighters and zippo firestarter tabs just don't stop to consider. Start with learning to use a firesteel and go from there.
Shelter. Sure most of us have tent camped. Have you tarp camped? Hammock camped? Tarp camping introduces you to many shelter building concepts without having to wriggle with the worms in a debris hut. Maybe you'll go onto the huts later.
Water. All kinds of gadgets available for purifying and filtering water. First focus on how to find it, then focus on how to make it potable. Gotta pot? Try boiling it after a makeshift cloth filter. Don't gotta pot, carve out a bowl in a stump, or use a natural depression in rock, fill it with water, then drop in heat stones (avoid river stones) into the water to bring it to boil. Or you can use one of those steri pens or chlorine tabs and save yourself the trouble.
Food - learn a few traps and be able to make snares out of paracord, bootlaces or brass snare wire that doubles as the bale for your little hobo pot. Look at those plants around and begin to open your eyes to the world of wild edibles. Make a rabbit stick and throw it at your neighbors cat (maybe not). Try catching some pan fish with just the basics of a little bit fishing line and some hooks that you might keep in your kit.
Navigation. Learn a few stars, including being able to identify the north style. Learn how to make a basic sundial and use the sun's movements to determine east/west (very simple). Consider taking a compass navigation course. Learn how to read a topographic map. This doesn't mean you have to throw the GPS out, but try just marking your camp position then shut the unit off and stow away. Use the map and compass for the day and only pull at that GPS if you need it.
Signal - learn some basic ground to air signals. Start to carry a whistle. Wouldn't hurt to consider tucking a bit of flag tape into your pack.
Other skills - learn so knots and practice them. You can keep a bit of paracord in your pocket and practice knots while on break at work.
Build a PSK and BOB. PSK = personal survival kit, its a little package that you build and store in a small tin or tupperware. You throw it in your pack and it has all the items you need to address basic first aid, shelter, fire, water, signalling etc. Its the thing that keeps you from forgetting the most basic stuff while packing for your trip. How small can you make your PSK and still have the basic items you will need? Rather than buy one off the shelf, build it yourself since it is so much cheaper and you will know its contents.
A BOB is a Bug-Out-Bag. Its often a back pack that you can throw in the truck. The BOB is kind for SHTF mentality folks. Basically, what if you had to evacuate your house RIGHT now. This Bag is somewhere you can just reach out and grab it. It is all packed and will see you through the next 72 hr or whatever after you've evacuated. You can carry a full BOB in your car/truck also.
Good luck and be sure to keep reporting on your learning adventures. There will always be stuff to learn and improvements to make on your road to adventure and skills development!
