A business owner has to be all things, especially when the business is new and there isn’t enough revenue to pay others to help. For me, I found marketing to be the most challenging. Attracting new customers, versus selling new services or products to existing customers is the lifeblood of the business.

It requires a large variety of skillsets. Analytical skills, and financial/accounting which are very different than developing new products, marketing and sales. Producing a product can have a variety of challenges also, either getting the work done yourself or managing others to do it.

In a mature field, there is a lot of competition, requiring a lot of work to stay ahead of others trying to take your business. In a newly developed field, there are a lot of unanswered questions, and a lot more risk.
