Nike’s “JUST DO IT.” branding (written about before, here) was powerful at its inception and it’s still powerful today. At least, it is for me when I’m feeling lazy about working.
In addition to the daily habit principle, it’s really good at cutting through elaborate excuses I have about why I can’t work on anything. Basically, simply, the phrase allows your determination to overcome your fear, if you hit yourself in the ego with it.
Sometimes it seems trite. It still can help get at least a little work done, and that’s what matters, day-to-day, week-to-week, month-to-month. Whether it’s the same project or several, well, you know.
