“As a matter of self-preservation, a man needs good friends or ardent enemies, for the former instruct him and the latter take him to task.” – Diogenes
Your friends are just as valuable to you as your enemies, provided that you love both. Love is not a limited resource; it can be given freely, without concern for depletion, so don’t be so sparing with it!
Bis vincit qui se vincit in victoria.

Your post makes me think more on what an enemy could be to oneself in regards to illness symptoms. It seems when such things arise they can be quickly perceived as an enemy would. It is good to think on loving the health that I have as a friend as well as loving any illness symptoms I may have. Loving with a depth of feeling in such a way brings encouragement and healing pathways.

Enemies can have their value if one resists the temptation to judge and resent them, although I’m not sure it’s always their ability to take one to task that provides the value! In fact, an argument could be made for the position that a real friend is one who can take you to task on a productive basis!
One way or the other, your suggestion holds true. Love is a radiant force, and it will bless or curse those who either welcome or resist it, without any valiant effort on our part. All of those dynamics work toward a creative goal if we are consistent and appropriate in the expression of love.

Love is one of those things that increases with use. Your friends have earned your love and your enemies probably need it!
