Giving them what they need

Hi Coaches,

I’m in CCP and coaching some clients pro-bono to gain as much experience as I can.

I’m struggling with believing I am doing and giving them enough. I know it’s because I want to feel like I am a great coach. I think I AM a good coach, but after a session where I feel like I didn’t give them very much, I question that and doubt it.

Does that mean I really don’t believe I’m a good coach? (Should I work on this?)
And most importantly: How do I know / believe I am giving them enough? How do I know when I need to improve, and when I can just rest on “I did my best, I gave them what they need to know.”?
