"perhaps i can really have a regular excercise routine....i'm beginning to believe that its possible...."
Yes you can! Yes you can! A friend of mine runs 50 mile races... he makes my 5-6 miles look like nuthin'... but my 5-6 miles is something, to me! Don't compare what you do to what others do... just do it, for you!

5-6 beautiful miles on a beautiful Thursday.
A customer tried to ruin my day earlier, it didn't work, lol, I just thought about my run and all was well.
Ha!
