Mission pivot, I feel like a fraud

For years I’ve been working in a particular space. Built a name for myself. Got invited to speak at events etc. unfortunately, there wasnt much money to be made. I enjoyed building products, which kept giving me work from a totally different industry. It kept growing and I’ve been able to build a flow of work where I continue to build products but for a different audience/industry. It’s paying well so I wanted to switch my business from focussing on the previous niche, to this new one.

But I feel like a fraud. Am I abandoning this previous mission just to follow the dollars? The work is the same. Enjoyable in both industries. The pivot would move me away from a mission into a new industry with not much of a north star.

I’m afraid I’ll regret it. Have I been an imposter all this time?

Any advice?
