I was diagnosed with ADHD as a kid. I received many different types of drugs and treatments that, IMO, didn't work. I barely passed the 3rd grade, failed the 6th grade and dropped out of school when I was a junior.
I was also a gifted artist, like my father, I could draw anything. I wasn't fantastic but it came easily to me. At 16 I picked up the guitar and quickly learned how to play and was proficient after a month.
These experiences made me question why I was good in some areas but failed in others. By the time I was 19 I gave up ALL drugs I was taking for ADHD and started my own treatment of "taking responsibility for my life."
This was the hardest thing I ever had done. At that time I was reading at a 6th grade level and has no prospects for jobs. I went to live with my grandparents and received the best education of my life. Discipline. They were farmers.
After 2 months I knew I had to leave and make a life for myself. I was scared and afraid but I had started reading self-help books and when tested again at the department of vocational rehabilitation I was reading 4-5 years ahead of my current age. My spatial skills were off the charts (their words).
I knew I had something special about myself that I could work with. I knew that if I worked hard I could do anything even if it took me longer to accomplish it I could do it.
I started by working my way up a janitorial company. I learned spanish in 6 months using Neuro Linguistic Programming techniques. I met my future wife and got married. I started putting computers together for the purpose of playing video games. I loved it. I was good at it. I eventually worked as a tech for a big box store and then worked in IT at a large insurance company when I found out I was going to be a father.
I learned everything I could about Active Directory. I then learned Perl as my first programming language and automated most of my job. I then started making games at home and learning as many languages as possible. I felt unstoppable.
Then my wife and I were having problems. Not huge problems but enough to get help. We sought counseling and happened to meet with a woman who studied ADHD as a specialty during her phD. Within 1 hour she said to me, "You know you have ADHD right?"
My heart sank. All those years of failure came rushing back to me. I thought it was crap. A ruse. A mis-diagnosis. How could I have accomplished so much. How could I have gone back to college and graduated with a 4.0 for my associates in comp sci and 3.8 for my bachelors. How could I learn all those languages and read over 500 books.
I had to come to grips with the fact that I still had it. But I made it work for me and it was unfortunately affecting my relationship with my wife. We were able to come to an understanding about who I am and accepting the way I think.
Now, I make games for iOS fulltime. From home. ADHD isn't a death sentence. It's only a disorder if it's making your life harder.
