Of the 7 1/2 habits of lifelong learning, I think that #1, "begin with the end in mind" is easiest for me. I doubt I could function w/o setting goals- I even time myself when I get ready in the morning (sad but totally true!).
#5, "Create your own learning toolbox" is the hardest for me. I like to fly through life fast and don't take the time to collect things along the way (to my detriment much of the time- sigh...).
