Yes - and Good For You... We should all start our own business... sometimes is it difficult - and sometimes it works.
If you are out of work and over age 50 - I strongly suggest finding a way to start a business - perhaps something you have wanted to do most of your life - but didn’t... We need innovation.
Think it through - do the research... Nothing like being your own boss.
I was my own boss but I fired that SOB.
BTW, I work with an 80-year-old who still works even though he could comfortably retire. We have special technical skills that are typically in demand, particularly by defense firms. I'm taking grad courses, on my company's dime, of course, to expand my knowledge and make me even more versatile in the job market when I start looking around for another position.
