Am I odd as an autistic person in not experiencing burnout?

From what I have read, not all autistic people will experience burnout, nor will all experience meltdowns and shutdowns. The term ‘burnout’ isn’t precisely defined and can encompass a wide range of experiences. Over the years, I experienced several periods of ‘just not being able to go on’ and I needed to stay away from work; it felt a bit like hibernation mode. I am much better equipped to manage my daily life now I’m retired. Perhaps it’s because I have more time to focus on my special interest.

I read so many posts about burnouts and shutdowns and it makes me question whether I'm truly autistic. I live a simple life. One to reduce stress to a minimum.  That's because I deteriorate significantly when stressed.

It sounds like you may have a set up which is somewhat suitable. There's nothing wrong with a simple life. I do think more people wished they had that. Not taking into account the paradox of heavy masking, neurodivergent people often do things their own way due to different social parameters. 

A few years ago I had imposter syndrome relating to something which wasn't autism. I learned you can compare yourself forever and a day to others but it doesn't get you anywhere. Everyone is different.  Accept yourself for who you are.
