Tough call ... my mom trained me to be right handed. I'm nearly ambi. Twice (at 9 and 12) I dislocated my right arm and wore a cast for 3 months, learning to write left handed, and function left handed. Today, I tend to still favor right hand for writing and some tasks.
My mom and son are both left handed.
In 7th grade my son finally had a teacher that had a clue what my son was struggling with. Her daughter about the same age was also dyslexic, so she did her masters thesis on it. I was amazed at the long list of related "dysfunctional traits" that dyslexics share ... better than half I relate to. In that list are ADD and ADHD, which I share with both my mom and son, but didn't learn that much about until I needed to learn more about my son's "disabilities" (or gifts), which are worse than mine.
I tend to self medicate with caffine when I need focus around distractions. But, I've never been able to function well in distractive environments, which included school and most cubical office environments, as I can not tune out the clatter of other people unless I'm "hyperfocused", at which point everything disappears in my world except the project I'm focused on (including phones, people trying to talk to me, etc). I've compensated over the years by working off-shift, frequently late afternoon into late evening, or from midnite to noon, so I have enough time with a less disruptive environment.
In hyperfocus mode, I used to work 72 hours straight without caffine, then crash for a 12-18 hour sleep as soon as the task was completed. Some times 72 on, 18 off, for monthss at a time. I've never been "solar", even today. At 55, three day days wear me down, but I still knock off 48hr days a few times a year with little trouble. You learn not to do new design on the 2nd or 3rd day, as that skill does get impaired, but I can still debug and correct problems on the 2nd/3rd day with little impairment. There are advantages to easily knocking off
100+ hr weeks with extreme focus and productivity, which offset struggling with a normal 8-5 schedule in the clatter of a normal work environment. I just don't expect the rest of my team to pull this off, they are not wired that way, and need to keep a solar clock to remain productive.I'm also analytically functional when asleep, frequently answering the phone and talking coworkers thru a several hour disaster recovery without waking up, and being unaware of it the next day. I've also driven asleep, and was pulled over once in california at 5am asleep. It took the officer over 10 minutes to get me to pull over, and several minutes more to get me to roll down the window, and answer his questions. At one point, he screamed at me "tired hell", and I woke up, to full alert in seconds. It took him a while to realize I was asleep and not DUI. This used to drive my college girl friend nuts, as she would "wake me" to go on a date, I would get dressed, talk with her, and never wake up.
Certainly, from this prospective, we are certainly not all created equal. And our weaknesses are just as likely to be our assets.
