Have to do something!

Ha, you sought complicating first, then i have to cut(我不得不断). '我得断' means i would cut. '不得不' is very useful when you want to say 'have to do something'. For example, i want to be Shodan, so i have to do more L&D problems. Then you may say:
'我想成为初段，所以我不得不做更多的死活题'.

想 xiang3: want
成 cheng2 为 wei2: a word means 'become'.
所 suo3 以 yi3: it's a conj. means 'so'.
更 geng4 多 duo1:m ore.
死 si3 活 huo2:death and life.
题 ti2: problem.
