serna vs. Serna

I’ve realized that I’m not always consistent with how I spell my name; sometimes I use a small “s”, as in “serna”, and sometimes I use a big “S”, as in “Serna”. The rule, in my head, is that it should be a small “s”, as in “serna”; any time I write “Serna”, I’m just breaking my own rule.

If I can’t even get my own name right, how will I ever get others’ names right?!?
