OP I recomend to start whit Bushcraft/Surival, if you have a friend that you know from the start of your life, try to get him into bushcraft.

I do bushcraft now for 4 years, and it's the most rewarding and peacefull thing there is. My best friend that i know for about 18 years now, joined 2 years ago, He doesn't regret it one bit. I showed him most of the skills that i learned in those 4 years.

Look up Ray Mears video's and other lads.

Read bushcraft books, and make your own exams, great way to learn.

And if you dont want to take your bushcraft books outside, just scan the pages and print and seal them whit a sealer , then you can take them outside. Great way to let your friend see what bushcraft is, and you always have reference pages whit you.

And you learn faster.

"The great thing about bushcraft is that wherever you go, the skills go with you."

"Knowledge is the key to survival and the best thing about that is: it doesn't weigh anything."

Just my 2 cents.

Good luck
