Wrong personality for IB. Alternative options?

It seems I'm just not a good fit for IB and my personality and my attitude are not a good match for the industry.

What other options are there for me?

I'm too entitled to do less prestigious jobs and would constantly be bitter and resentful for not getting into IB and would just become really apathetic, which would show during my work. 

My initial academic background was shit with my bad A Levels and non-target undergrad, but I did get a first class degree and get internships/experience in finance (although non-IB), and I am on a master's course at LSE. I've done the best I can to move forward from my A Levels and it still feels like it's not enough.

My personality isn't changing anytime soon and I am not going to ever consider significantly less prestigious jobs. I would be fine with something lower than IB like AM but it still needs to be quite a prestigious role.

Will I end up unemployed permanently? I was told by someone on here that I am unhireable  and will never get anything, and it got me thinking - I know my academic profile is mediocre compared to a guy with 4A*s in A Levels and a first class Cambridge undergraduate degree, but surely an LSE master's will get me a role somewhere decent?

In the scenario where I genuinely end up with absolutely nothing and zero offers, am I just supposed to try again the next year? Graduate schemes have a limit of where applicants have to be within 1/2 years of graduating. If I don't get any offers this cycle or the next then I'm completely fucked and wouldn't even be eligible to apply ffs.
