Staying focused!

I didn't feel like running this morning at all. Just the thought of doing it made me tired.  I remembered I had a bad habit of focusing on the end instead of the beginning.  I remembered that it was better to do something rather then nothing.I ended up doing 2 miles today and was satisfied with that. 
A few years ago, a physical therapist who was treating me for my back problem told me that I tend to set my goals too high and I try to reach them too quick.  With that in mind I am giving myself until the end of august to reach my 3 mile goal.
Am I still setting my goals too high? I can't help but wonder. What the hell, I can always change them if I have to. 
I kinda wish I had insurance. Then I wouldn't have to worriy about dr bills piling up, and I wouldn't have to keep the visits to a bare minimum. That's life I guess.
God Bless you all!
