Can't hold a note to save my life

Hey guys and girls,

I'm new at this, 2 weeks worth of singing practice and I wonder what I'm doing wrong.

I just learned that what I'm doing is called vibrato but I don't know how to not do it and that's an issue. Any help would be highly appreciated. 

Thanks,

Robert 

Vibrato is a good thing, Robert! Here's an article I wrote on vibrato (and common issues with vibrato): https://www.30daysinger.com/blog/vibrato-what-it-is-how-to-develop-it-and-common-issues
