You need but two things, all else are wants not needs. You NEED a burning desire to do this adventure. You NEED a complete inability to admit defeat (defeat is not the same as lack of success) Defeat is running for shelter when you wake up with stiff legs a flat tent and soggy oatmeal AGAIN...
and these two needs are the least prevalent in today's gear-dependent hunter
Bestowing wisdom and moral purity, even on the unworthy and unwilling... especially upon them.
An ignore list??? Wouldn't that defeat the whole purpose?
