Weve grown up listening to norms set by society. These norms are presented to us as sacred laws. Break them, and you are labeled outcast. Well being called an outcast excites me. I would feel proud if Id be labelled as an outcast.
The most feared thing is what would people say? Well I say screw people and follow your heart. At the end of the day its your happiness that matters.
If in the eyes of society being a doctor is the only respectable job than that shouldn't stop you from following your passion of becoming an artist or musician.
obviously it doesn't mean you should do illegal stuff or harm other people.
Remember the time when any self-respecting parents would do everything to prevent their children from becoming actors? Yup, neither do I.
The point is, society can only have progress if a certain level of dissent is tolerated, otherwise you end up with something like the Matrix. That's how women got to vote and work, how monarchies gave way to democracies, etc...
