Quality of enemies ...
You should know someone by the quality of their enemies. The Arabic proverb was a little bit more gender specific. But, to whomever, it still applies. If you have not acquired the occasional adversary then maybe you are not doing enough.
The trouble with low quality enemies, they lack the mettle to give you something to fight for. However, those who have a bit of bite tend to provide a fulcrum to push forward.
I have been wondering if I actually have any decent enemies.
