It’s safe to say that book bloggers love lists: not only do we keep a thorough list of everything we read in a year, but we also leap to check out every new top 5/10/50/100 or thematic book list that’s posted so we can see how many of them we’ve read. And then, at the end of any year, most of us put together our own best-of lists, often for a number of categories.

When I was younger, though, I took the list-making to an extreme. As I was going back through boxes of mementos in America a few weeks ago, I found stacks of hand-written records I’d kept. Here’s a list of what I used to list:

• every book I read
• every movie I saw
• dreams, recounted in detail
• money I found on the ground
• items I bought or sold on eBay
• gifts given or received for birthdays and Christmas
• transactions made through my mail-order music club
• all my weekday outfits, with a special shorthand designating each item of clothing

Age 14 (1997-8) was the peak of my record-keeping, and the only year when I faithfully kept a diary. I cringe to look back at all this now. Most of the dreams are populated by my crushes of the time, names and faces that mean nothing to me now. And to think that I was so self-conscious and deluded to assume people at school might notice if I wore a shirt twice within a couple of weeks! My diary isn’t particularly illuminating from this distance, either; mostly it brings back how earnest and pious I was in my teens. It’s occasionally addressed in the second person, as if to an imaginary bosom friend who would know me as well as I knew myself.

What’s clear is that I was convinced that the minutiae of my life mattered. Between us, my mother and I had kept a huge cache of my schoolwork and craft projects from kindergarten right through graduate school. I was also a devoted collector – of stamps, coins, figurines, tea sets, shells, anything with puffins or llamas – so I obviously felt that physical objects had real importance, too. It’s a wonder I didn’t become an archivist or a museum curator.

Why did I save all this stuff in the first place? Even as a teen, was I imagining an illustrious career for myself and some future biographer who would gleefully mine my records and personal writings for clues to who I really was? I’m not sure whether to admire the confidence or deplore the presumption. We all want to believe we’re living lives of significance, but when I take a long view – if I never have a child … if I never publish a book (though I think I will) … if human society does indeed collapse by 2050 (as some are predicting) – it’s hard to see what, if anything, will be preserved of my time on earth.

This is deeper than I usually get in a blog post, but these are the sorts of thoughts that preoccupy me when I’m not just drifting along in life’s routines. My nieces’ and nephews’ generation may be the last to inhabit this planet if we don’t take drastic and immediate action to deal with the environmental crisis. Many are working for change (my husband, a new Town Councillor, recently voted for the successful motion to declare a climate emergency and commit Newbury to going carbon-neutral by 2030), but some remain ignorant that there is any kind of problem and so consume and dispose like there is (literally) no tomorrow.

My home is a comfortable bubble I hardly ever leave, but more and more I feel that I need to become part of larger movements: first to ensure the continuation of human and non-human existence; then to improve the quality of human life, especially for those who have contributed least to climate change but will suffer the most from it. I have no idea what form my participation should take, but I know that focusing on outside causes will mean less time obsessing about myself and my inconsequential problems.

That’s not to say I won’t listen to the angst that’s telling me I’m not living my life as fully as I should, but I know that working with others, in whatever way, to tackle global issues will combat the lack of purpose that’s been plaguing me for years.

Appreciation for my past can only help with bolstering a healthy self-image, so I’ve kept a small selection of all those records, and a larger batch of school essays and assignments. Even if this archive is only ever for me, I like being able to look back at the well-rounded student I was – I used to get perfect scores on calculus tests and chemistry lab reports! I could write entire papers in French! – and see the seeds of the sincere, meticulous book lover I still am. As Eve Schaub writes in Year of No Clutter, “I’m not about to stop collecting my own life. It has been a source of pleasure for me ever since I can remember; it helps define me.”

A selection of favorite mementos I discovered back in the States:

In high school I started making my way through the American Film Institute’s list of Top 100 movies. I’ve now seen 89 of them.

I kept a list of new vocabulary words encountered in novels, especially Victorian ones. Note trumpery: (noun) attractive articles of little value or use; (adjective) showy but worthless – how apt!

As a high school senior, I waded through Ayn Rand’s The Fountainhead to write an essay that won me an honorable mention, a point of interest on my college applications. Though I find it formulaic now, it’s a precursor to a career partially devoted to writing about books.

I planned my every college paper via incredibly detailed outlines. (I’m far too lazy to do this for book reviews now!) Can you work out what these essays were about?

As a college sophomore I wrote weekly essays in what looks like pretty flawless French. This one was an imagined interview with Charles Dickens and Thomas Hardy about the autobiographical and religious influences on their fiction.

Are you a list keeper? Do you have a personal ‘archive’?

How do you balance a healthy self-regard with working for the good of the world?
