It's interesting to see other people collecting that many items... I can hardly name 30 items that I want to have (not including clothes), but that probably just depends on the personality. Then again, being able to put everything you actually need in one big suitcase, is a nice benefit.
Really? No equipment-related hobbies?
My list has at least 15 items that are basically dedicated to hiking. (And I could probably do with a couple more on there)
That includes equipment - 6 items for paddling, 2 sets of weapons and a guitar. The rest is just electronics, travel bags, books (around 20 items, so it makes ~30 in total).... can't think of anything else.
I'd be hard pressed to split my radio station into even 10 separate items, and that's probably my most equipment-intensive hobby.
And about equipment related hobbies, I have like 100 electronic components in separate boxes , I lose the challenge right there
In the wake of "Up in the air", nice film I recommend, that opens a few doors without being over the top. Just enough to start your own thoughts.
