should I take the Entrepreneur training?

I have a full time job in Corp America but want to build a full time Life/Weight Coaching business, I am on the wait list and plan to go the the 1st training session in 2019. My question is would it be a good use of my time to go through the Entrepreneur training now or would it make more sense to wait til I’m ready to start building my business?

Thank you
