To some extent, yes. Both that I don't have the skills, confidence or social abilities to work with others to have got to where I originally wanted in my career. Plus, it's creative, so computers have basically decimated the industry.
However, some of it is an assessment of reality to be fair. Jobs in my industry can see people travelling up and down the country and doing 16 hour days. So then it becomes- do I actually want to live like that? Erm... no! Do I want to be plankton level in a sea of sharks? Nope! Do I want to be ruthlessly exploited- Nah.
I've become better at realising that the small niche I managed to carve for myself is probably the best I can hope for and maybe it's for the best for me anyway. That said, it's still so bloody difficult to sustain financially and physically now. I'm older and less motivated than I used to be and it's just not giving me what it used to. So, on multiple levels really, my dreams are collapsing.
