Wise word I learned a long time ago

I have spent most of the morning battling with myself because I slept in and I was getting very harsh with my thoughts.
And then I remembered a Doctor, once told me When this happens STOP and think would you talk this way to a very good friend." Never" I said I wouldn't ever speak that way to a good friend. Then why do you treat you self less than a good friend.
I admit it stopped me in my tracks because I suddenly realized sometimes I was the only friend I had.
I know myself better than any one else in the world, and I am worthy of respect and compassion from my self. Instead of castigation I will think of ways to motivate myself in mush more reasonable terms, instead of anger and frustration.
It a good day.
