Read David K. Reynolds passage from page 5 of Constructive Living:

You see, the fully functioning human being isn’t someone who is utterly free of pain and happy all the time. Not at all. The mature human being goes about doing what needs to be done regardless of whether that person feels great or terrible. Knowing that you are that kind of person with that kind of self-control brings all the satisfaction and confidence you will ever need. Even on days when the satisfaction and confidence just aren’t there, you can get the job done anyway.

Can you just do it?
