When the NRA wants to prevent gun reform, they funnel money into the campaigns of candidates nationwide to make sure they don't vote for common sense gun reform. Insurance companies do the same to block Medicare for All and prevent us from guaranteeing health care as a right, not a privilege.
Success is not defined by money or status, necessarily, but by how many people you've impacted and how fulfilled you feel with your decisions. If you can garner all of these things, then more power and success to you, but all in all, you must feel happy and satisfied with what you personally have put out into the world.
