A project doesn't have to be unique as a whole. You can always take an already existing idea and add your own twist to it (new UI, new feature, better optimisation, etc). What's important is actually doing something instead of being stuck in an infinite loop of brainstorming idea.

And if you want to travel cheaper, youth hostels are very affordable. Though you are not garanteed to have a private room, it's perfectly ok if you just want a place to sleep imho

Sounds a lot like "it's not my problem until it actually affects me personally".

I don't know why people want to avoid paying as little taxes as possible when it basically improves the infrastructures/services in their own communities.
