i've been too passive through most of my life, but particularly through my teenage years.
this meant that i picked easy option A-levels and uni degree, which i wasn't really passionate about or motivated to do well in.
this followed on into my working life.
in addition, i stuck in what wasn't really a healthy relationship for too long, eventually getting married and having children, getting to a point where extricating myself was impossible.
this led to an extremely difficult period, which caused DW and me a lot of hurt. we have worked through this now, and are in a much happier place, so at least this has worked out ok eventually.
but professionally, i turn up, do my job well enough to avoid losing it, but have no motivation or enthusiasm for it. my responsibilities are too large to start something new (and would have no idea what anyway).
weirdly though, this passivity is only about my own feelings/needs. i work extremely hard at home, sharing all the workload there, and have put a huge amount of effort into making my marriage work.
it frustrates me no end, but is too late now.
