Finding my Impossible Goal

Hi there- I am a teaching performing cellist and have just made a new website- the cello guru. I give tons of content ahead of time in the form of instructional videos, and also videos of my own music on FB and You Tube. My goal this year is to make 100k teaching. My impossible goal is to get 10,000 subscribers to my You Tube channel and or to get 10,000 likes on FB ads. Is that an ok goal, or should I be focusing on the money aspect, like the goal could be to make 300k this year? It is definitely impossible seeming as well. Thanks for your insight here!
