Asking for recommendations

As a coach, what do you think of asking past clients to recommend your services to people they know who might benefit?

Do you think that’s good practice and a smart thing to do, or is it better to let happy clients spontaneously tell their friends?

I imagine it’s all about the mindset in which you do it (needy/pushy vs. value-creating/abundant) but I wonder what your practice was like when you were still coaching one-on-one clients without a waiting list. 🙂

Thank you!
