麻烦帮我看看这段英语有没语法错误

my major is japanese.i have no idea which position i will be at after graduation,But if possible,I would try to do all kinds of jobs and to live and travel in different cities,At least when i get old, I should have stories to tell my children and let them know that my generation was also very interesting.but Everything is hard to predict, You will never konw what will happen in the future, just like I have never know why I would take japanese as my major.

that which position i will be 。 That去掉。
predict后面用句号。

其他OK的呢。
