If you are already ambidextrous, good for you. Skip this one and eliminate all of your goals instead. Now for the rest of us, this is a simple, but not easy way to awaken some dormant cells on the other side of your brain. It really does make things different, not necessarily better, however. If you brush your teeth with your non-dominant hand you’ll probably do a pretty crappy job but think of all the new neural pathways you’re generating! I have no idea what the biological benefit of that would be other than to make your teeth feel fuzzy all day.
There are lots of other fun things to try like putting your pants and socks on the other leg/foot first. I bet you didn’t even realize you always put one particular leg in first, did you?
Wait… I feel a personal anecdote coming on…
In college I studied Graphic Design and Illustration. I’m terrible at drawing and I hate it. My Fourth year Illustration teacher hated me too. The feeling was mutual. He once told me that the drawings in my book were the kind of stuff were were doing in First Year. I wanted to punch him. We were forced to submit sketch books every quarter and were expected to fill them. This is actually much worse than it seems, it was agony for those of us who despised sketching. We would panic and start filling our books two days before they were due.
Halfway through my final year I was failing illustration and I needed the course to graduate. One late night, a few days before sketchbook D-day, I was sitting in my room fuming over the harsh words from my instructor when I decided to unleash my contrarian ninja and draw with my non-dominant hand (which would be my left). I used a few magazine photos as inspiration since I suck terribly at life drawing (at which point you might wonder why I was in art college in the first place). I scratched out a few drawings and was relieved to have at least put in a good effort. Maybe I’d get one of those green ribbons for “participation”.
The next day I nervously handed my book to the evil illustration teacher. He looked at a few drawings and asked, “What’s going on here, this is quite different from your other work?”
I told him about my deviation. “I figured my drawing couldn’t get any worse,” I said.
“This is brilliant! Why didn’t you start doing this earlier?”
Later that year I passed illustration and graduated with a degree in Visual Communications. I haven’t touched a sketchbook since.
