Well, if you got Bill Bryson's book for Christmas , you might one of the 1,000 plus hikers who will strike out from Springer Mt this spring.
Blood Mt. Georgia
Before you head to Dick's* to buy the $1,000 worth of equipment you will need, you might get real and visit this ATC page first.
And then get in shape, prepare your diet, save about $5,000 in 2023 dollars. practice backpacking in 100 degree weather, freezing snow and ice, a week of raining eating the same kind of food and so on. Oh yeah carry enough water in case of draught (2 pounds a quart/liter).
*or better yet, REI, EMS or the local outdoor store in your community like Shawnee Trails Wilderness Outfitters.
For that matter hike the River to River Trail or some local long distance trail (100 miles or so) to test your mental and physical ability.
