Like a grocery list, you sit with pen and paper and look around and think about what it is you really would like.
Rather than jam and milk, you might think about a month in Peru in their summer, hiking the Inca trail, spending two weeks on a quiet beach on Zanzibar or walking part of the Great Wall of China.
You can write out the qualities of the perfect partner for you or the outline of the book you want to write. You might also note down the fitness level you would like to maintain in your 40s, 50s, and 60s.
It’s quite a powerful process to write these things out and bring them to life. You’ll feel better for the process. Then you can organise when and how you’ll do them. Then go and enjoy your dreams while you can.
