The physics of following your dreams, or bees in a beachball

This article was posted on my facebook feed. The goal-setting advice of the article aside, isn't the physics wrong?



If you're a bee in a beachball, flapping your wings and pushing in one direction, wouldn't you be pushing an equal force in the opposite direction so the ball wouldn't move?



Or .... hmm ... the wing motion would I guess disperse the force of the air in multiple other directions, cf with you (as the bee) pushing in just one direction, so that might indeed cause it to roll?
