Can I become ambidextrous

Can I become ambidextrous just by starting to right in my other hand

I found an interesting site about becoming ambidextrous, check it out if you'd like:

I didnt think that I could be anbidextrous till my art teacher told me to experiment by doing a portrait with my left hand, turns out my left hand drawing was better than my reight hand as you tend to concertrate more with it. try righting with your normal hand then with your oposite hand, it takes concerntration, but it should work. time consuming as anything and its fun, because you can laugh if it all goes horribly wrong.

yep. you can
studies even show that if you right with your opposite hand youll be that-handed instead.
but yes, it doesnt tak very long to learn either...just lots ans lots of practice...I used to do it whan I was bored.
now I can can write with both hands...as well as mirrored, upside down, and one upside down and one normal! lol
