Some colleagues I have, take 10 vacation trips an year. Apparently its all about spending time chasing some hobby like photography. Apart from the fact that they spend insane money on camera and lens gear, you also have to spend money to travel, accommodation, food etc.

The funniest thing is most people don't use some lenses more than a couple of times. And they don't even see their photographs more than once. What's more, no other human will ever see their work.

All of this is fine and dandy during a phase when you are young, have energy and a job that pays well. All this money could go into a retirement fund. Someday its all going to end, and these people will blame government and societies for not doing enough about the 'free money' they think they are entitled too.
