Being a successful professional with ADHD sucks. Everyone assumes that just because you've gotten this far in life, then ADHD can't be that bad or disruptive to day-to-day life. In reality, I spend every waking moment of my day balancing the expectation to think linearly (ie "normally") with the expectation that I'll contribute unique insights that are made possible by the non-linear thinking that is a hallmark of ADHD.
It's exhausting.
