Struggling with niche


I am in the process of setting up my business and whilst I understand that it is important to have a niche for marketing purposes, I do not want to niche completely at the moment.
The way I would like to describe to potential clients what I do is as follows:
Adult humans that are stuck in their life and / or career due to overwhelm, stress and negative self-talk.
Do you think that can work as well? I believe it does, but would love to hear comments from more experienced coaches.
