返事はありがとう。先週の週末、先生を私が聞きました。あいにく、先生は私の母国語があまり分かりませんから、元の意味は違うかもしれない。「人生は願い事をすることができない。」先生がとう言いました。
Anyway, I'm switching back to english so you guys can understand me better, since I'm not even close to being average in japanese.
Thank you all for the responses. I decided to ask my japanese teacher (who happens to be a nihonjin), though there's a possibility that what she told me isn't accurate because she doesn't fully understand my mother tongue. What she said was an accurate translation is what you'll find in the first paragraph. I realize now that you guys point at it, that 願い事 might be a bit too pompous for what I'm trying to say, and perhaps I might used the word incorrectly, taking its meaning too literally.
