I have so many dreams. where do i start?

when i was young,my dream was to swim in the sea but i have down that now,a few times.

I dream about dancing till sunrise in a reggae bar, somewhere in the Caribbean would be nice. 
I’ve always wanted  write to a novel,  run a marathon, and visit the Great Wall. Not at the same time! 
I’d love to learn to ski one day... and  speak another language, like english.
