First: less guilt (especially important as I had a Catholic upbringing). Before I believed that I am failing at being an adult, and that my parents were right that I am too messy, chaotic, etc.

Second, getting help. I got the most from HowToADHD YouTube Channel, the "Driven to Distraction" book, and conversations with friends having ADHD and working in tech (some other life situations are no that relevant).

Third, started taking Modafinil. It helps me a lot!
