Thing #1

My most challenging habit would be #3 - view problems as a challenge.  Not understanding something the first time or having something not work could lead to frustration.  Rather than viewing them as problems, if I think of them as challenges the frustration would go away.  I am always ready for a challenge.

The easiest challenge would be #1 - begin with the end in mind.  I do well when I understand and see my goals.  Knowing the final outcome can help me accomplish the small goals along the way.

I think the most important habit for me would be #4 - have confidence in yourself as a competent, effective learner.  I am always telling my students "you can do it, you know this".  I need to practice what I preach.
