Am I good enough…I want to become a Scholars Life Coach

I just listened to Podcast #334 and realized I have been coached with 4 out of 5 of the coaches on the podcast. I had an excellent experience with them. I was just coached by Marlene 3 days ago and after the session, I was so wishing I was goof enough to do this. I tried to do a model around it but can’t get past the thought “I am not good enough and am too old” (I know, that’s 2 thoughts. I don’t seem able to get an action that will take me in the right direction. Can you help?
