Web design certificates

[Superwoman]

I have about 5 or 6 websites that I personally design and maintain. As of now I have no intention to design websites for other people. Do I need to get some web design certificates if I want to be my own web designer of it is enough if I just self-educate myself?
And if I want to design for other people/companies? Do I need to get some cert of web design certificates or it is enough if I just self-educate myself.
Any response or comments will be greatly appreciated,
Thank you very much,

Re: Web design certificates

A Certificate will makes you "believeable" as Simon Cowell likes to say!

Your 5 websites lend support to your capability.
