Sometimes it's benficial to perform a value spot-check.
I realise that the things I've done in the past that seem to grow in significance and value are:
Journeys made
Things I have built
Books written and published
Pretty much anything I've written and published
Practical problems solved
Things I don't value so much
Prizes won
Money earned
Praise garnered
Books, poems and pictures made but unpublished or unexhibited
Time spent indoors
I think one insight is make sure you publish or make public in a way that people appreciate the things you make. Don't just let them clutter up the hard drive.
And build things.
