how much does 'the thumb' matter?

it is funny to me....well not funny, really....how i can get 50 'thumbs up' on my YouTube videos....in total... and 1 'thumbs down' on my videos....and what do i focus on?  right....the one 'thumbs down'....seriously?  
back to the 'You Are Enough' meditations!  
i am having a blast creating 'mailable art' right now....i will be sitting in front of the camera in the next couple days with a brown paper bag, images, gesso and chalk pastels....
i will not let that 'thumbs down' stop me!
have a great day!
