Time management

I look at my running log and I find that the frequency of my runs have been consistent across the last two-three weeks, i.e. 2-3 runs/week. This is definitely not enough but I am not able to fit in more runs into a week that has only 7 days. The grad school is definitely a learning experience on how tight schedules could get. Now that I have gotten adjusted to the demands of the grad school, I just need to bring out my time management skills and get those elusive runs in.
