Maybe cooking?  I think it's very interesting,  and if I should master it,  I would be able to make what I like to eat. 

That would be quite happy! At least a man with the skill of cooking can have a meal time that depends on himself.

And if I 【should】 master it

That's quite formal. Maybe "could" can suit the sentence better. Of course you can also just cross out it, then "master" can keep unchanged or be changed into "mastered".

回复 @啊啊是谁都对：Okay

回复 @lizhenxuan：At least "should" is grammertically correct.

Sometimes I also hope I could cook well, because then I could eat good food even if in deplorable conditions
