A bit more on the topic of consistency now that I am feeling less frustrated with myself.
I should build consistency the way I have built confidence by being consistent. I have a touchstone for this already, this blog. I consistently write it every weekday and have for over a year. This is a place to start.
The next step is to create other areas in my life to be consistent. And I need to change my self image. I need to think of myself as some one who is consistent, who follows through and who is the person I want to be. If I can see myself in those terms I will succeed.
