Saving in the short-term only to pay more in the long-term.3. Pride:
Failing to utilize and recognize the good work of others.4. Lust:
“Overdoing it” in certain areas and neglecting ones.5. Envy:
Desiring features that you don’t really need.6. Gluttony:
Configuration files are too “bloated,”resulting in loss of efficiency.7. Wrath:
Ignoring complaints and feedback, getting caught up in “getting it done.”
