Part time job to alleviate the boredom a good or bad idea?

I (29M) have worked as business development / inside sales B2B in the corporate sphere. My last employment dated back from summer 2023. So I have been a NEET for a year and a bit now. Due to my vulnerability towards psychosis, I could not hold down my employment for very long (max. 1 year). Recently I have been thinking about taking on a part time job which would be easier than the jobs I did in the past. I applied for part time cashier at a supermarket. Is it a good idea to take on a part time job to alleviate the boredom when NEET. Or will the easier job just be mundane and won't help my boredom?
