Intent is everything because it puts forth a desired outcome. Instead of letting life take its course - que sera sera - predefining what you want helps to transport you towards your goal. In time management this kind of intent can be very helpful. A while ago I wrote a blog post on the elasticity of time. This elasticity comes to play in time management. Setting a goal of what you want to accomplish within a certain timeframe sets the framework, after that let the universe help you. You need to be very clear, though, in stating what exactly you want to accomplish, and define the timeframe clearly. Putting it in writing, such as on your to-do-list, is better than just thinking it in your mind. An example might be "I must get to the airport by 1PM," or "I will finish answering all my emails from yesterday by 10AM." Give it a try, I know it works.
