Be wary of offending with your growing sense of superiority—you will need your allies.

Compensate for the drug-like effect of success by keeping your feet planted firmly on the ground. The power you will build up in this slow and organic way will be more real and lasting. Remember: the gods are merciless with those who fly too high on the wings of grandiosity, and they will make you pay the price.

~ Robert Green, The Laws of Human Nature
