Translation of "Todays" in Japanese

Todays lunch depends on the mark I get in this test.

今日の昼食は試験の点数に掛かってる。

"I think it is exhausting, but todays troubles will surely be rewarded" "Don't say such half-minded things, even if you don't believe them completely."

「しんどいと思うけど、今の苦しみはきっといつか報われるからね」「適当なこと言わないで！ そんなこと自分じゃ全然思ってないくせに」
