Taking a class or furthering your education can be an excellent idea. If you truly feel guided to do so, if it excites you, if it adds to your life or career, then go for it! But do not use study as an excuse to procrastinate what you know you are meant to do.
As a human being, there is always more to learn because life is a continual process, so you needn't be perfect in order to teach or share what you know, and the chances are you are ready now! Be honest with yourself about which applies to you.
We love you, your Angels
