No, it's not silly. It's great to be able to give other people that gift.
But as a goal for yourself, it does run a risk of putting too much power over your dancing in the hands of other people. Different people respond differently to the same performance, even to the top dancers. For every performance you've seen that you thought was great, there will be some people who see it and don't like it.
IMO, a better goal is to dance the very best you can and in a way that makes you feel happy and satisfied with yourself and your dancing. That has the advantage of being a goal that you can meet every day and reset for the next day. It takes a very long time to become a great dancer, and if that's the only thing that will make you happy, you'll have to wait a long time to be happy! But any day you know you did your best and that was better than your best last month can be a great day!
Good luck!
