I still have two more difficult exams left, but I'm trying to __________________; after these I won't have any more for a year!

The blank needs an idiom meaning to focus on positive aspects of a difficult situation.

Option 1 -> look on the bright side -> means to focus on the positive aspects of a situation despite difficulties.

Option 2 -> think upon the sunny side -> incorrect preposition and unnatural phrasing; not a standard idiom.

Option 3 -> look forward to the bright side -> incorrect construction; mixes "look forward to" with "bright side" unnaturally.

Option 4 -> think about the sunny side -> not the correct idiom; "sunny side" isn't used this way in English.

When life throws you lemons and you're facing tough challenges, you can choose to look on the bright side - focusing on the silver lining rather than dwelling on what's going wrong. It's like being a glass-half-full person who finds hope even in stormy weather.
