… made a suggestion.

I asked a friend who had recently started a new life-coaching business:

“What do you say when somebody asks, ‘What do you do for a living?'”

Her answer was pretty concise (two sentences), but it was mostly about her qualifications and methodology.

A better approach, I think, is to focus on the specific problem you solve and for whom:

I help seniors navigate the healthcare system.
I help adults with ADHD be more productive.
I help small business owners buy and sell their companies.

Word of mouth works by people telling other people about you.

At this initial stage, nobody cares how you bake the cake or what makes you qualified to do it.

The people who are ready to hire other people have very specific problems. Position yourself as the solution.
