I agree, and also physical health too. Poor physical health can lead to poor mental health.
I went through a similar experience this year. Finally got myself checked after I’ve been called “lazy” for so long, which immensely effected my self appointed value. I finally got my ADHD meds, and my productivity went through the roof. I tend to think what could’ve happened if I discovered my problem earlier, but Im happy that it at least wasn’t even later.
I just redid a bunch of old code I wrote years ago it was pretty hacky and unpleasant.
Why?
I was feeling good about what I was doing and I just kept going. I was on a roll.
Many of the changes that were on my list to do that day weren’t directly related but I was in a good mood. Things are working so I did a bunch more.
When you get that good feeling it makes a huge difference in the outcome.
If I had felt bad or overwhelmed, I probably wouldn’t of been nearly as ambitious.
In my case, having ADHD and going undiagnosed for decades (I only got diagnosed last December) has caused me to blame myself and my conscious actions for things directly caused by the neurochemistry of my brain. This year may have been my most productive ever.
