Official time and Personal time should be different and mixing them together should not be encouraged.

If you are given a Special Assignment to do in office; nothing wrong if you take it home to complete in the weekend but it must not be every-time and must not be all office work.

When it is Saturday or Sunday, some people will still carry unfinished office work to their house to complete, not knowing that office work can NEVER finish.

As you are working very hard for your organization, always work hard to build yourself. Because of office work, some people don't have time for themselves, parent, friends, family. Some people will say their girlfriend/boyfriend left them, people don't know that Relationship get mind. (If you don't water your plant, what do you think is gonna happen?)

Finally, don't devote all your time on official work. When it is your free day(s), always create time for yourself, go out, have fun, meet people, do anything good but away from office work.
