I agree that this is prevalent. I wish that people would focus more on what you wish to do? what you are good at/passionate about? what you feel would be a rewarding career for you? rather than whether it is a male/female role. We can always change our minds in the future but a mindset can be difficult to change if it is ingrained in your psyche. Society has transformed so much and we have made great strides- it is a pity that an individual would sacrifice a rewarding career based on what other people may think.
It is something that really needs to be addressed in society as a whole- this does not solely come from peers but is an attitude that is prevalent in society. Perception and perspectives need to change- many careers that will be common in the future have not even been realised. This may be an opportunity to quell this stereotype notion in the future.
