What's the best way to lie about a six month gap in employment if I've just been sitting on my arse?

What's the best way to lie about a six month gap in employment if I've just been sitting on my arse?

I've heard the typical illness, started your own unsuccessful business and went travelling excuses, but which of them works best? Are there others?

Family emergency/illness

Say you worked for 6 months but got fired

Say you had to revaluate what you wanted out of a career and did some self learning and low-key shadowing here and there. I work in HR for a large state agency where we get 100+ applicants for every position and I filter out resumes all the time. 6 months isn't a big deal at all and wouldn't even cross my mind as a flag desu.

Extended vacation.

>I traveled the world to find myself

why not lie and just say you worked your previous job those 6 months?

Illness

I haven't had a job. I graduated university with a meme degree about 5-6 months ago and didn't bother looking for work anymore after I started getting turned down for shit minimum wage menial jobs.

School/Learning
Vacay
Lie about dates.
