I suggest you do take a survival course. I know a lot of people who took Tom Browns course and learned quite a bit. For someone that has little to no real life wilderness survival knowledge this would be a good start. It gives you a chance to learn and do.

Also, I reccomend preparing survival kit(s) and first aid kits to carry on your person and in your vehicle and "bug-out" bags for your house. Also, you should look at what you carry on you everyday and where you go everyday. Do you carry a flashlight, knife, ect? Can you or do you work somewhere where you can carry these things?
Maybe going on camping trips every once in a while can help you to realize what you could do better.
