50 before 50

This idea popped up on FB today & for a change I've decided to give it a go. I have long enough that I'll need to average one thing every 2 months, so it seems possible.

( Ideas so far! )

Suggestions for the rest are welcome & will be considered, however off the wall they are! I'm not promising anything, though ;)

I'm writing all these in a tiny Paperblank notebook - it's A7 and I'm putting each thing on a separate sheet, so I have room for thoughts / ideas / etc. It feels very grown up & not at all my usual lurching from crisis to crisis, leaving a trail of destruction in my wake, car crash of a lifestyle. You never know, I might end up actually feeling half way to being a grown up by the end of this.

(Edited for suggestions so far.)
