After you have succeeded in establishing an early morning devotional time, you can see about having devotions at other times of the day as well. In his book A Serious Call to a Devout and Holy Life which is available at amazon.com, William Law recommends praying no less than 6 times a day. In other words, prayer throughout the waking hours at three hour intervals. Not counting before and after every meal of course.
Since you probably have work or school (or both) to attend to, you will need to be creative. Ask if you can take an hour off for lunch and spend the extra time in prayer and meditation. Or wait till you get home, if you're blessed enough to get off at three or before and pray then. Sometime between noon and three pm is ideal if you are able to get away.
