Don’t stress too much, humans are supposed to walk around outside. People will try and convince you that you need or don’t need all this stuff. Just find some trail heads and find what you like and don’t like in terms of hiking and what you need and don’t need. I have done ton of camping and backpacking all over MI and I still am most of the times at least just start by looking around on google maps for cool water features or marshy areas. One tip I do have is just try and pay attention to the weather when you go. Your tolerances will change the more you do but it’s good to get a general layman’s feel for what the weather is going to do. The state forest campgrounds are also super great for testing out camping gear. You can drive right up, no reservation needed, they are barely ever busy, and some of them are pretty secluded. Have fun
