Little by little

I am trying to discipline myself to jog 3x a week and to make things more structured, I searched the net for a jogging program which end result could help me run a 5K marathon. Like what I posted days before, my first jog wasn't the best. It was not structured and I was quickly wasted. So far, when I tried the program, my first day wasn't as it should be because I prolong my walking. By the way, my program alternates my jog and walks for a minute or so. On my second jogging day, I was about 2 minutes off the program. I wasn't sure if this is because of my timer (I was using my iPod to estimate the time, not knowing that it does have a stop watch) or I was giving more time to my walking. However, last night, I made it a point to stick to the program and I was able to finish my whole 20 minutes. I used the stop watch and really pushed myself to jog. I know that I still have a long way to go, but I'm gonna do it little by little.
