No doubt you have a reason for phrasing the question like that, but I'd say a more relevant question for most starters is "How do you avoid frustration when starting a new cleaning company?", and someone in this forum (I'm new & don't know how to quote, yet) hit the nail on the head - Either be brave, and with a business plan, or, equally valid, start part time - ie have another source of income so you're not completely dependant on the new business. That's what I did, and I wouldn't change it - frustration happens when you're under pressure, so do what you can to keep the pressure off.
