$ whois Hardmath123

I am a student who loves to write. I started this blog back in high school, writing about whatever happened to interest me at the time. Of course, those interests have shifted over time, but the theme of this blog has been quite constant: that there is treasure everywhere, in even the most mundane places, and it isn’t buried deep. It is yours, as long as you take care to look out for it.

Hardmath123 is my alias on the internet. It was chosen in a much-regretted burst of spontaneity when I was young[er] and [more] foolish, and has inextricably linked itself with me since then.
