Plan 10 things to do before a big birthday

Help me plan 10 things to do before a big birthday.

The birthday: [e.g. 40, next September]
Things I've always meant to do: [e.g. see the Northern Lights, swim in the sea in winter, learn to make bread]
Rough budget for the whole year: [e.g. small, a bit, or a figure]
Time I can give: [e.g. one weekend a month]
Who I'd do them with: [e.g. alone, my partner, my oldest friends]
Things I don't want: [e.g. nothing involving heights]

Before you start, ask me up to 3 short questions if anything important is missing. Wait for my answers.

Then:
1. A list of 10, mixing big, small and free, each fitting my budget and time.
2. A month for each so they're spread across the year, with the big ones spaced out.
3. The first small step for each (book, ask, buy, practise), with when to do it.
4. Three ways to mark the birthday itself that tie the year together.
5. A simple way to keep a record, like one photo and one line each.

Use only what I've told you, and leave prices blank for me to check. UK English.
