I grew up writing and using my left for everything but occasionally, I've been caught using my right hand just as well so personally, I don't know lol- I practically subconsciously being ambidextrous. I would use my left hand as my dominant hand though, yes, and it's not easy. I'm currently a Freshmen and having to write notes, essays, sports, gaming, or basically anything requiring hand coordination where most of your peers are right-handed is tricky but it is something new. I see right-handed people struggle so hard with using their left hand but I and every other left-handed people I know, I guess we are forced to learn to use our right hand but at the same time, we don't drop using our left hand so I guess it's good to use a left hand. It allows a chance to be ambidextrous but that's just me and like I said, I practically grew up being ambidextrous if that is the correct phrase for being dominant in left and right hands.
