What experiences are worth paying for?

I compiled a list of activities that I'd like to do this year at least once. I'm 21, if you're older than me I would love to hear what you think.

So far I've got: - Get a proper haircut - Go to a concert - Go to the skate park - Buy (and ride) a bicycle - Go and get driving lessons - Go to the beach - Take a long train ride out to the country

I guess I'm looking for more 'one off' things I should try before dying, that are budget friendly instead of broader lifelong suggestions like 'pick up a language / go to gym / learn new hobby'.

Please throw me recommendations relentlessly regardless of how 'dumb' you think they may be.
