As with many things in life most things are not necessary. From a Sales Expert perspective I would look at this perhaps differently than others.

There are many life coaches that you have to compete with. How would you like to differentiate yourself from them? When researching your competition do they have specific certifications that they promote? If not would you having certain certifications set you apart?

I always think why do my customers buy from me? Taking that a step farther I actually ask them, "You have a lot of great choices in our market but you decided to do business with me. Can you explain to me why you made that choice?" My favorite answers are;
I feel like I am your only customer
You actually asked me that question
The difference between you and everyone else, you care
Even if you can't solve my problem you help me find someone who can.

If you are trying to decide to go into business no matter what you have a product to sell. In this case you are the product. If you ever want to brainstorm. Feel free to give me a call.

Make it a great day!
