This is unfortunately incorrect. For example, the difference between the typical Fluid Dynamics that all MEs take and Continuum Mechanics is huge. It isn’t typically something one picks up on the job as it requires learning a completely new math (Tensor Calculus). You either have that depth or you don’t. It will lead to opportunities that those lacking it will be locked out of.
I’m not saying that creative writing is not the right choice for the OP. What is indisputable is that it will come at a cost. In any curriculum saying yes to something means saying no to something else.
