Hi. I would say two types of translations. 1. Not so natural but translate each word, we call 直訳(ちょくやく): 勉強（べんきょう）することは難しい（むずかしい）けれども、面白い（おもしろい）と私（わたし）は思い（おもい）ます。 2. More natural Japanese, we call 意訳(いやく): 勉強するのは難しいですが、面白いと思います。 Hope this helps.

Maybe you should start by trying to express yourself in English first, then perhaps you could ask for help in translating it into Japanese.
