I have the same passion as you and the first time i heard about clarity i asked the same question, because i wanted a way to impact other people's lives. I think clarity is good, and i think it can provide a lot of value to people, and you can actually build a business here because the market is good
Of course, there are a lot of consultants in that niche so you have to make yourself stand out. It definitely has a great market. Everyone wants to be more productive and manage their time better. If you can show people how to do that and simplify it for them there is plenty of money to be made. This is one of the better sites for building such a business. Linkedin Sales Navigator is also an awesome tool for this.
Having played both roles of public speaking and time management for many years, I can honestly say there is definitely a market for this.

It all boils down to how good you are at selling your services and finding clients. As others have said, there is a need for this type of service, question is whether you are able to convert that need into clients.
I would start by doing some market research on how to find potentials and how to convert them into real clients. Only after you have an idea how to do this and, the effort required, can you decide if this is really for you. There will be questions regarding your credentials and why you are so good at this. Also, do not forget the value-add for your clients, how will you ensure they are getting value for money (and that they are aware of it).
It is always worth pursuing your passions! If public speaking, or consulting is where your heart and soul are calling you to go, find a way to get there! Push hard, learn as much as you can, and pave your own road to where you want to go.
