Personal growth before life coaching certification?

This is my first month in scholars and I am soaking it all in like a sponge. Very quickly I have felt that I have also FINALLY found what I really want to do in my life – coach others. I was sharing with my best friend and she said, ha ha, you will finally get paid to do what you do in every encounter in your life. This is what I am made to do. 😀 I have just started overdrinking program and am working hard to constrain myself to focus on that and see success before moving on to overeating. Then I want to do money, entrepenuaers… give it all to me! My question is… how far do I need to go in my own self growth before jumping into life coaching certification myself?
