For the first few years of setting up my business, I'd get really triggered by people asking me for information about the kit I had chosen to use. It felt like they were trying to hack the years of experience and tens of thousands of pounds I've invested in skilling myself up to do what I do. I learned over time that is is not the case at all. In fact people asking these valid questions probably fit into any of these groups:

1. They were trying to hack my approach and would probably never appreciate the time and money I've invested in getting to where I am. In which case giving them the answers was not really cause for concern in worrying about creating competition.
2. They have a personal interest in HOW I do what I do and want to begin their own unique quest into an area that is similar but can never be the same.
3. They share a problem that I had and have overcome and actually operate in a wildly different market to me, serving totally different people but the problem we both had is the same and I can help them quickly to solve it to support a fellow small business owner.
4. They're just nosey and like to know all of the components and details about most things in life.
