How to find the motivation to study when you don't like the thing you're studying?

I felt this way tonight when studying my language lesson. I almost quit. I carried on with it for two reasons. I imagined being in that country – and I hope to be – having some knowledge of the language, and how helpful it will be contrasted with how I felt when I was there, and couldn’t communicate. The second reason was timing. I set a small period of time to study, and that helped knowing I could stop, and put it away (until tomorrow), once that time was reached. So in effect, my motivation was the potential benefit of my study, and time.
