What else can I do?

Every time I look at my 5k training plan, I look at some of the upcoming workouts and question whether I'll be able to do them.  But then I look back at where I started and what I've accomplished since then.

I used to think that I couldn't stand heat and humidity.  It turns out that I really hate the pair of them, but I can stand them, and I can even jog in them.  I know that I can, because I did.

I used to think that I couldn't jog near people who weren't in my corner.  But I did, so I know that I can.

I used to think I that I couldn't jog in new places.  But I did, so I know that I can.

I used to think I couldn't jog all the way around the track.  But I did, so I know that I can.

I doubted my ability to do all these things, and here I am doing them.  It makes me wonder what else I'm capable of. 

Will I jog that entire 5k in November?  Will I get this extra weight off?

I guess I'll have to trust the pattern.
