I’m writing notes for myself and I can read them. When I’m writing for someone else (which rarely happens for handwritten notes) I take the time and effort to write nicer.

Also, I specifically didn’t write the example carefully because the use case for me would specifically be handwritten notes I made for myself.

I like dotted paper, the dots are less distracting than grids, lined paper sucks for sketches/etc. and with plain paper I’m missing guides. But I agree that on this particular one, the dots are a bit too prominent.
