stupid is as stupid does

eight deadly sins of the stupid smart person
1. impulsiveness (doing something rash)
2. neglect (ignoring something important)
3. procrastination (actively avoiding something important)
4. vacillation (dithering)
5. backsliding (capitulating to habit)
6. indulgence (allowing oneself to fall into excess)
7. overdoing (like indulgence, but with positive things)
8. walking the edge (tempting fate).
