Talking about Enjoy in Duty

How to make duty become enjoyable activity? This question often come to me. After I think, one of the way is consider that what we do is way for entering heaven and save from hell. In the other words, we do it for ibadah and dakwah, and not only think that it's duty...duty....and duty that we must finish it. No!!!!! Not only like that. if we think like that, it will make us in pressing. Yeah,,,,,it's "hikmah" that I get for today. May this can give many advantages to us. Amiin....
