Pictures you choose will appeal to you for some intrinsic and extrinsic motive. Yes, they will be about where you lived, how you lived, whom you loved, who loved you.
Most importantly, they say something about your perspective, your point of view, your angle of vision in your own life.
Let me illustrate this concept through the picture above.
The camera is looking at both the water flowing, and the big boulders in the way.
The eye is moving upward, following the movement of the water.
The boulders are part of the passage the person is making through this territory to get to the next stage.
They are not impeding movement, they are to be navigated around or over.
For me, these boulders represent what we encountered, will encounter, as we flow like a river to the sea!
The images and the overall metaphor are ancient, classic.
Was your life a garden of delights? A torrent of desire?
Keep an image in mind as you choose pictures and artifacts that tell the story of your life through your experiences, your vision of what you hoped it would be, and how it turned out, and how you survived.
p.s. you don't have to chronicle everything. Choose what is most meaningful to you.
