Salt-Refrigerator981's journey

I'm 39 and feeling a bit stuck after being self-employed for nearly 4 years. I lost a $70K job in web/content due to restructuring, and since then, I've been running a few online stores. Unfortunately, my self-employment isn't bringing in consistent income, so I'm at a crossroads trying to decide my next steps. Ideally, I want to scale my business, but I know I can't rely on it full-time right now. I'm considering whether to return to full-time work or take a part-time job to supplement my income while I figure things out. I have a solid educational background with 10 years of post-secondary education in business, finance, insurance, and graphic design. My work experience spans banking, insurance, healthcare, and IT, but I've also done retail management over 15 years ago. I don't enjoy corporate environments or sales, and I've stepped away from graphic design outside my self-employment. I prefer roles that involve more movement and interaction. Recently, I found a part-time grocery store admin/systems role just 5 minutes from my home, offering $18.60/hr. It seems straightforward—do the job and go home—which I like. However, I'm uncertain if taking a role like this would be a wise temporary step while I sort out my longer-term career direction, or if it would just be a waste of time. I'm looking for guidance on whether I should pursue this part-time role or consider other types of jobs that might align better with my situation.
