1) Maintaining a steady job in an industry in which
that person is not the "norm"
2) Performing in an area in which that person is
essentially not accepted, but managing to perform the task at hand anyway (without missing a beat despite the hate).
3) Being present in a place which is deemed basically as hostile, so that others who look different (or are different) can also
potentially gain access to that field (albeit always in limited numbers).
