That's a challenging question.
For my part, like most here (I suspect), I never formally took up bushcraft.
From childhood onwards I always enjoyed being in the outside - playing on the farms when my mum was fruit picking, live-action role-playing as a teen, medieval re-enactments in my 20s, and across it all was camping out in the local woods.
I never 'got into' bushcraft, I think I probably always was. Or maybe never.
So if someone came to me and said they wanted to take it up and how to go about that, I'm not sure I would have an answer. Not the kind of answer they were looking for anyway. I'd probably say something like, 'then spend more time outside, and absorb yourself in it'.
Which I agree may sound a bit abstruse and vague.
But that's all I can think of.
I wouldn't say, 'buy yourself a knife, a stove, and a few pans. And enrol at a bushcraft school.'
No, I don't think that is the way into it at all and will just lead to frustration and totally misses the point.
But for the life of me I can't think of a way someone would formally take up bushcraft.
Yeah, I think I would just say, 'go out and enjoy yourself and take time to relax and think'.
That's the best I can come up with.
I just don't see bushcraft as a hobby. Not a distinct hobby anyway. I just don't see how someone can say, 'this weekend I'm going out to do some bushcraft'. That would leave me dumbfounded.
