Caveat: This is supposed to be humorous. But like a lot of humour, there is very much an element of truth to the following. If you think your behaviour matches anything in the following list, but the first emotion you feel is anger towards me, you're obviously a dickwad in denial.
1. Anything can be contained if you hide it well enough: There is nothing wrong with hiding mistakes or misappropriating blame. Just don’t get caught doing it. This can apply to your personal life as well as your professional one. The best option is to blame it on someone who isn’t around to defend themselves. Remember: deniability is your best friend. If you get caught out, blame training, equipment, technique or anything else except yourself. Finger-pointing is great exercise too.
2. Hypocrisy starts at home: Yep, it really does. Never let it be said you can’t have your cake and eat it too. In fact, if you have the cake, make sure you let everyone see you eating it. Don’t try to be the change you want to see but force it on your children or those closest to you. They will grow up feeling repressed and constantly like they owe you something (refer to Point 6 for further information).
