this is just the adventure of life the ups and downs. (people jousting for position amongst their peers)
i will say this for those who are about to brag about cutting people off and being lone wolves ok, but no man should be an island and one of the laws of power is that "one should never be isolated".
one of these philosophers said quite eloquently that "people who have wronged you are like tripping over a stone, its their nature not your nature so you can never be mad at a stone". something like that.
