I'm somewhere on the autism scale, I've had multiple vague diagnoses but only one in particular from a neuropsych who attributed my specific form of ADHD (auditory) as likely caused by autism. For me, rounding out the end of my 20's it feels like my energy / motivation is reaching an era of "wondering if I should press the gas as I'm careening towards a yellow light on the highway going about 78mph in a 60mph zone". In the past, I've had trouble really laying out complex tasks in a way I can get them done, and encountered crippling procrastination and blocks to just starting things. Stimulants have helped but only marginally, it's quickly becoming kind of a existential crisis as friends have accomplished more than me and I largely attribute my lack of success to a lack of focus and well... just being unable to get that much done in any given day. Comparing to friends in my group who think I'm smart is the most painful. I definitely make below average as a dev in the US, and for two years of a roaring economy I did okay but feel like I've largely been passed by my friends / colleagues who can actually force themselves to try. I'm starting to worry that as time goes on, I'm actually moving down the class ladder and it's starting to really scare me. Curious if anyone else has dealt with this? Preferably in a way that isn't just "accepting you don't know how to improve"?
