Why lit?

I envision that my writings will light (and also) lit up the minds who are reading it, including myself. Hopefully, these writings may be the source of information and also acts as my writing portfolio.

Lit also means “very good, enjoyable, or exciting” in the Cambridge dictionary.

I don’t claim my writings with “very good, enjoyable, or exciting” but it will be a bonus to me if it ever becomes “lit”.
