> Focus is essential for productivity. Do whatever it takes to get there.

I'm posting this because it's something I went through in my career and I hope it helps someone who is in a similar situation

I was undiagnosed ADHD until my 30s. In high school and university I was able to brute force my way through and get reasonably good grades. I had a really rocky start to my career in software. I was always getting middling performance reviews along the lines of "You're really good when you're working, but your productivity is terrible". Meanwhile my stress level was crazy high despite not exactly doing lots of overtime or anything else

Even treated, ADHD can make focus very difficult. Undiagnosed, it is devastating

Bringing it back to the words I quoted, I agree entirely. Focus is essential for productivity. Part of doing whatever it takes to get there might mean getting diagnosed and medicated
