The Father's Letter

It has been a year since the grand piano arrived, hulking in the living room like an anchor. At first, I thought it was excessive. Wasteful. A misallocation of scarce resources. But then I would walk past and see my son there, shoulders hunched, brow furrowed, hammering out notes that made no sense to me, and yet he looked alive in a way I had not seen before.

I have spent most of my life worshipping rigor. And rigor has served me well. But rigor does not explain why my son's crooked smile at the keyboard makes me feel more than any of my spreadsheets ever could.

I wrote him a letter.

Dear Son,

I do not know if I have ever really explained what I do.

I spend my days helping people help animals. I do it with rigor, with spreadsheets, with models of the world that let us see more clearly where our efforts matter most.

When I was young, math came easily to me. I liked how reliable it was. I liked how, if you put in the effort, you could get better, sharper, closer to truth. I found the scientific method beautiful in its precision.

My parents were not scientists. My mother was a hippie, an anti war activist, and an advocate for the poor. My father was an accountant who said little about politics, and little about much else. They divorced, as your mother and I have, and I grew up in a town where practicality was a survival skill. The idea of being an artist was not just dismissed, it was mocked.

So I went into science. I carried with me the belief that if the world is burning, you do not have time to play. You pick the fire where you can save the most lives. If ten houses are burning, and one holds twenty people, you go there first. That has been my compass. It is utilitarianismUtilitarianism is a philosophy that judges an action by its consequences, aiming to do the greatest good for the greatest number., before it was called effective altruismEffective altruism is a movement that tries to do the most good possible by using evidence and careful reasoning about impact, rather than instinct alone..[1] And it is often heartbreaking. Because you cannot save everyone.

When you asked me for a piano, I demanded a proposal. It was clumsy, maybe even cruel. It was my attempt at teaching you the skill that has helped me survive: how to make a compelling case, how to ground desire in fact, how to stand in front of the world and say, this matters.

I should have been more tactful. More gentle. I should have made room for your excitement before demanding evidence. For that, I am sorry.

You have taught me something this past year. Watching you play has reminded me that faith belongs at the beginning of every spreadsheet. That inspiration is not wasteful. It is the reason rigor matters at all.

Please know: I am proud of you. Not because you might one day be a pianist, not because you practice, not even because you stuck with it. I am proud because you try. Because you let yourself love something openly.

Play your piano. Make your music. If it is a hobby, that is enough. If you want to take it further, I will be here, not just with charts and figures, but with curiosity and love. And if you ever want to talk about how music is math, or how business sneaks into art, I will be eager to share what I know.

But for now, know this: I love you. I am grateful for you. And I am glad we are on the same team, even if sometimes we stumble in how we talk to each other.

Keep playing. Keep smiling.

Love, Dad
