self inflicted pep talk needed

I'm a full time mother of two.  To some this may seem difficult and to others they may wonder how that could possibly keep me in the 'full-time' work status.  To both groups of people, it is sometimes difficult, but not for the reasons I used to think and to the other group of people, it isn't always full-time, but it is always on-call, which makes for some very long nights and little planned down time.  That is why it can seem overwhelmingly fatiguing.
So, with the daily task of 'work', I need my pep talk.  I usually call my mom because she's good at that stuff.  But really that pep talk needs to come from within.  I'm not gonna lie, it's been a struggle lately.  I want to say that I always feel productive, beautiful, successful, happy, and positive with a game plan to become increasingly better.  Yet, I find the productivity lacking, the dowdy woman emerging, the unsuccessful days increasing, all leading to disappointment in myself and negative thinking.
Well. What do you do, I ask, when you need that pep talk and you find only yourself to give it to you? the solution lies within. 
I know at a much younger point in my life, I thought that pep talk was supposed to be from the spouse.  As nice as that is, it's the same as hearing from your mother, sister, father, friend or anyone else who loves you.  What I have learned is that I need to be self motivating.  I need to be self reliant.  I need to have the same amount of love for myself as I do for others. 
Truly, I think the pep talk comes in the quiet moments.  I'm sure that's why some people take long showers.  That's why some people press the snooze button.  That's why some people actually like doing the dishes alone.  That's why a lot of chores happen, frankly.  And that's why I like to run. And I run with no music.
the long point of this? my knee hurts for some reason so I haven't been running consistently.  Therefore, I haven't been consistently pondering and giving that personal pep talk. It's amazing how one small thing can trickle down to every aspect of your life. 
The solution - well, I'm running anyway this week, even if it's slower than normal.  So far, the pondering makes me breath more, think more clearly, and enjoy my children and my life in general.
