Definitely as I get older I have less tolerance for drama or any other BS. One that I really have zero or less tolerance for is people's self-inflicted problems. Don't come crying to me about your problem that you created for yourself.
As for being FIRE status, it has changed my outlook at work since now I don't let it affect me. As I say all the time, my attitude is don't give a sh!t. I do a good job at my work and contribute my share or more. But I am not worried about promotion, getting involved with office politics or drama, and have no career aspiration goals. I am here for the paycheck and benefits. Basically every 2 weeks the company evens up the score.
One thing that I have also noticed, I have much less patience than I used to. I hope this changes once I am fully retired and not working. For now I want to maximize my time to do things I want, so unnecessary waiting is very hard to tolerate.
