Right now I'm reading all over the questions/articles I can found related to this question. But I can't find a similar problem or solution to mine. So I would like to comment mine here. In my case, I really like my job. All my teammates are great people, and I like working with them. Everything seams nicely. But my problem is that I don't work hard enough, (It's not that I'm actually working hard but want to push myself more, I would be very happy if that was the case), I really don't. Do you have any suggestions?
