So, this question is a little unique. So the last few jobs that I have worked weren't actually just jobs, I was also the business owner. So the biggest challenge that I faced as a business owner was marketing and sales, and I have come to realize that I am just in a place in life where I don't want to have to worry about that anymore. So my biggest challenge was finding the right way to market my business, my businesses, so that I would draw people in, and the outcome was for one of my businesses, so I had two businesses, one was a bookkeeping, a virtual bookkeeping company, and what I realized with that business was that my social media marketing was not to draw people in, it was just to keep me relevant with the people who were already following me. What I found out was that my business mostly came from referrals, or from people who had been long time lurkers, or people who followed me would recommend me because my business name was catchy, it was a referral type business. For my other business, my online business manager business, that one really just never got off the ground. There wasn't, I don't think I had a clear enough idea of what I was doing there. So to resolve the problem for the OBM business, I ended up closing it, just because I am ready to not worry about sales and marketing, at least for my own business.
