Ok, as a writer, kudos for putting a good book as the first item on your list, well done :)
As much as I hate fiat, until the crypto revolution is realized, I'd say having a little bundle of extra cash stowed away somewhere is always a good idea. Sht always seems to want to happen, money seems to lubricate much sht away ;)
Thanks for your comment and yes, a good book is an excellent element for a good trip.
And clearly the money is just and necessary for whatever we do.
Regards :)
