I've spent plenty, but would I do it again? Of course! Hobbies are what I work for. They're my release, and at the end of the day they are the things that I love to do and which keep me sane. Why wouldn't I spend necessary funds on them?
My next door neighbour thinks that it's more important to pour money into the garden or house than a silly hobby like "astrology". That's his prerogative! I disagree.
