The first couple hours of the day are the most productive in terms of sheer activity. People check in, catch up, and knock off some simple tasks. At this point, it's all about maintenance and making sure there aren't any fires to put out.
Don't accuse yourself of being lazy or being a procrastinator and ask: Why is this so difficult? The fact that you're finding it hard to make yourself do something is a sign that maybe you should be doing something else.
