Do I always have to be present for my business to succeed?

Dear Dr Pesa,

I am a 32-year-old housewife and mother of three. I have been trying to start businesses over the years but they keep failing. The one that lasted the longest was about 6 months when I was running a boutique. I’ve tried catering, events management, daycare, grocery store, tailoring and several others but they never take off and when they do, they don’t survive very long. I always end up closing shop due to meagre returns and few customers. The other thing is, I am not always at my businesses. I hire people to help me run them. Is that why they are failing? What should I do?
