…outright sabotage.

It doesn’t matter how talented you are, how great your connections are, how much money you have. When you want to do something – something big and important and meaningful – you will be subjected to treatment ranging from indifference to outright sabotage. Count on it.  – Ryan Holiday, Ego is the Enemy, 63

…ego avoids such feedback…

The art of taking feedback is such a crucial skill in life, particularly harsh and critical feedback. We not only need to take this harsh feedback, but actively solicit it, labor to seek out the negative precisely when our friends and family and brain are telling us that we’re doing great. The ego avoids such feedback at all costs, however. Who wants to remand themselves to remedial training? – Ryan Holiday, Ego is the Enemy, p41-42
